    If the part you are looking for is not immediately available or has been discontinued, we may be able to offer a suitable substitute for your current and/or for future orders. We also offer custom design services.
  7. What do the letters in the Hollingsworth part numbers signify?
    The prefix letters designate the terminal style and tongue type. The suffix letters designate barrel style and length and insulation type. For further help, please see Hollingsworth Terminal-ology.
  8. Do your terminals come in different wire sizes?
    Hollingsworth terminals are available in wire sizes 26 AWG to 4/0 AWG. The larger wire sizes are made upon request, for a minimum buy quantity.
  9. Are your connectors brazed?
    Ring terminals, Butt Connectors, and Spades are brazed. The wire size # 8 and # 6 Butt Splices are made from flat copper stock and brazed. The wire size # 8 Parallels and larger are all made from seamless tubular copper stock, so they do not require brazing.
  10. What is the wire Strip length needed for my terminal?
    The wire strip length needed for a Correct/Crimp is listed on the label located on your terminal bag. The wire should protrude from the barrel a minimum 1/32″ – 1/16″ maximum.
  11. Are your Terminals RoHS Compliant?
    Hollingsworth manufactured terminals are RoHS compliant.
  12. Do you offer tin/lead plating?
    Electro-Term/Hollingsworth does not offer the tin/lead plating of terminal lugs. Our compliance with RoHS requirements excludes lead plating in our product line. However, we do offer customized plating, such as gold, nickel, zinc, etc., upon request.
  13. Can your terminals be used to splice multiple wires together? If so, will it still meet UL standards?
    Our crimp type Pigtail and Butt splice connectors are UL listed as splicing wire connectors – to be used to splice multiple wires together and still retain their UL approval. The Quick Connects and Wire Connectors are listed with UL as single wire applications only. They can be used to splice multiple wires together, but will not retain UL approval.
  14. Do you have a Warranty on your tools?
    Hollingsworth hand tools carry a one-year warranty against workmanship. Damage due to improper use is not covered.
    Hollingsworth semi-automatic tools carry a one-year parts and labor guarantee.

  15. Are your tools calibrated?
    All of our tools are calibrated. A certificate of Calibration is issued with the tool prior to shipping and is good for 1 year. The tool must be returned to Hollingsworth for recalibration to maintain current UL/CSA status.
  16. What is the temperature rating for Hollingsworth insulated terminals?
    Standard Hollingsworth insulated products are rated up to 105°C. For High Temperature insulation, please contact the factory.
  17. What is the Tensile strength of my part?
    Tensile strength varies per part. Please refer to Pull Charts.
  18. Can you provide a +/- tolerance to assume for the W dimension (.314” nominally)?
    The tolerance on the W dim is + or – .003. We always try and work to nominal size or to the low side of the tolerance.
  19. We need to know the ECCN (export control classification number) details to make sure if China is able to get from US and keep record. Would you pls provide the ECCN information for us?
    The ECCN for Hollingsworth manufactured terminals is EAR99 (no license required).
  20. What are the pull test requirements for Fully Insulated Slip-Ons Part numbers XS09787 and XS09778?
    Part# XSO9778
    22 ga wire min 8 lbs.
    20 ga wire min 13 lbs
    18 ga wire min 20 lbs.
    Part # XSO9787

    16 ga wire min 30 lbs
    14 ga wire min 50 lbs.
    These are the U.L. recommended minimum pull test requirements.
  21. I was hoping to inquire about part number R4171F; we’re looking for this style of terminal ring on a reel. Do you offer this part on a reel? If so, what is the part number? How many per reel?
    We do offer this part on a reel. The part # is R4171FT. The “T” signifies the ring terminal to be assembled on a reel. The reel size is 24″ dia with 2000 pieces per reel.
  22. RE: Splitting terminals at crimp operation. We are using terminal R64662B and crimping with Tool H20. We are having an issue with the ring terminals splitting inside the crimp. See pictures. If you could please provide information to why this might be happening, it would be appreciated.
    I am going to ask that you crimp the terminals with the barrel seam side in the rounded (radius side) of the crimp nest. This will stop any seam opening. It appears that the indenter (male side of the crimping tool) is coming down extremely hard on the brazed seam.
  23. We use quite a bit of your ring terminals for our large UPS systems. Do you have 3D cad files?
    I’m afraid we do not have 3D cad files of our terminals.
  24. Do you have dimensional crimp data for these lugs? Meaning, what is the size and length of the crimp using your tools? 1/0 lug R8303BFN blue, 2/0 lug R8321BFN yellow, 3/0 lug R8338BFN red?
    The crimp type is a four indentor and the length for all three sizes is .480″.
  25. We purchased item # XR1858SN (Description: LUG FAST ON STUD-8 22-18AWG). Recently, we received the lot where there is color difference on the coating. The old lot we have previously was with light red coating, but the recent lot we received was with dark red coating. Just wondering, is there any PCN (part changed noticed) on the color changed? Is the dark red coating permanently starting from new lot onwards?
    There has been no part change to this part. The industry standard for the insulators on these parts is red. We had a few customers inquire as to the pinkish color of the nylon. We just added a bit more color concentrate to our nylon to give it a deeper red. Other than the color concentrate being increased there has been no change to the part. The materials are all the same.
  26. I am looking for the crimp height specifications for a crimped terminal using the Hollingsworth 270 model. Is there a spec for an insulation crimp height?
    I want to start off by saying that Hollingsworth is approved through U.L., CSA and the Government MIL STD AS7928. Our products are approved via die nest geometry and not by a crimp height. The ultimate approval for a correct crimp is achieved by using the correct die and then obtaining the proper tensile pull strength once the terminal has been crimped onto the wire being used as approved via U.L. and Government standards. Using crimp height for an approval method is subject to many variations such as correct part being crimped, whose part is being crimped etc. Our dies are approved only for our parts.
  27. Can you tell me when the H270 machine being used was last calibrated?
    The standard practice here is to calibrate the machine once per month to ensure the integrity of the machine and the terminals being crimped on it.
  28. How much current can a SO9413 crimp connector handle?
    All of our terminals are designed to handle the max current of the wire they are designed for. The SO9413 is a 12-10 gauge terminal, so it can handle the current rated for 10 gauge wire. That would be about 30 amps.
  29. Do you supply a terminal that can handle 50 amps (@45vdc)?
    To get to 50 amps you would be using an 8 gauge wire. At that wire size, you would be looking at a ring terminal or a lug. There are some power disconnects that can handle the load. They are pretty good sized, but no flag terminal I know of. You could also wire a small relay into your circuit.
  30. I’m trying to find a minimum pull force requiring for terminal R4271S; I can’t find it in your web page; could you assist with this info? I need the crimp height and pull force requirement to verify my terminals are correctly crimped.
    The tensile pull force is determined by the gauge of the wire being used.
    The following are the U.L. ratings for 22-16 ga wires.
    22 ga. Min pull test is 15 lbs
    20 ga Min pull test is 19 lbs
    18 ga Min pull test is 38 lbs
    16 ga Min pull test is 50 lbs.
    Hollingsworth terminals are approved through U.L. and CSA standards of acceptable crimps based on the crimping die geometry and tensile pull strength. We do not use crimp height for approval. Using crimp height to determine proper crimping is subject to a variety of variables such as who’s die is being used, what type of die is
    being used, I.E., hex crimp, indentor crimp etc.
  31. Has Hollingsworth part no. SO5320SF-T (fully insulated slip-on terminal) always been RoHS compliant?
    The Hollingsworth terminal SO5320SF is RoHS compliant. The make up of these parts has not changed in 15 years.
  32. We are currently using the terminals with part numbers R4141SF and SO5305F in a product and are testing this product for agency. Would you be able to send me a copy of UL’s conditions of acceptability for these parts?
    The U.L. file #’s for these parts are as follows.
    The SO part # is file # E70344.
    The ring terminal file # is E31304.
    These can be found on the U.L. web site. The test procedures and acceptable limits and tolerances are referenced as well.
  33. Can you please confirm if your item P4130B is still active? I was notified by one of your distributors that it was obsoleted and replaced by item P4130-4.
    That is correct.
  34. I am wondering if P/N XR5109 is active and what is the tool require?
    The XR5109N is still an active and popular part #. The U.L. approved tool to crimp this terminal is our H6E hand tool. The correct wire strip length is 3/8″.
  35. Do I need to use the “N” at the end of the P/N? and What is the difference?
    The ” N ” denotes the nylon insulator. We see this quite frequently. Electro-Term/Hollingsworth used to produce the XR5109 using a PVC insulator. This had been changed quite a few years ago to the XR5109N (Nylon). If by some chance you still have stock on the old part # (XR5019 ) with the old PVC insulation, the hand crimping tool is the same for both parts.
  36. Do you have a female test tab similar to H133 that accepts a .250 x .032 tab?
    Hollingsworth no longer makes this part due to a lack of interest in it. I would recommend that you contact J.A. Jackson Corp in New York. The # is 1-800-892-2611.
  37. Hollingsworth component, part number B4067SN, in at least one of its systems, and needs documentation demonstrating RoHS compliance for this part.
    The B4067BN is RoHS compliant.
  38. I was needing a parts diagram for a H-270 unit. Of particular interest is the front guard and switch area. Also are these type of parts currently available for this unit.
    These parts are still available for sale. I believe the operations manual has the photos and part #’s you are looking for. Do you need a manual? I do not give out the drawings for these machines. They are proprietary to Electro-term/Hollingsworth. Is this a leased machine or do you own this? If it is leased, and it is in need of repair, we will repair it for free. This includes shipping charges as well.
  39. Customer is looking for your p/n SF20751SB , I understand this is not a valid number. Could you please suggest a part number per the attached. Please also provide price/delivery.
    This part is a good example of a bad design. We dropped it more for poor performance than for low sales. The problems arise from the width, .292, minus the stud punch, .198, equals .094, and that divided by two equals .047, the width of the flanges. That means that the flanges will fit into the barrels and frequently do during tumbling after brazing and during plating, with the plating causing the most trouble; the parts came back with about half stuck together and bent, due to the softness of the brazed parts and the thin and therefore fragile flanges. The heads would bend and were subject to all sorts of distortion, meaning most were scrapped.
    In order to improve the part, there is room in the stamping die (148) to make the head wider (progression is .420), but how wide would be too wide? There is probably room to make the head up to about .380 wide, but would it still fit the applications? That is the question Sales and Marketing could not answer in 1995, which is why we stopped making them, and that’s where we are today. So yes, you can make them “as is” and probably scrap half or more of your production, or you could make improvements in the tool to keep the parts from locking together, but would the cost be justified by the sales and how wide do you make them?
  40. We are redesigning a product using B4067SN. Is this part RoHS compliant and is there a CoC available?
    I believe the part you inquiring about is our B4067BN. (22-18 nylon insulated butt connector). This part is RoHS compliant and readily available. C of C’s available upon customer request. They are sent with the packing slip.
  41. I have a few questions about crimping a right angle quick connect terminal. I need to crimp a right angle female QC that accepts a .032″ x .250 tab” and crimps onto an 18AWG wire, and it must have built-in strain relief (such as an insulation crimp). I have identified two parts in your catalog that seem to fit: SO9405 SO9479S I see that for the SO9405 you specify the H12 hand crimper and for the SO9479S you do not specify any crimper. However, I cannot find the H12 in your catalog. Also, does that meant that you don’t supply any means for crimping the SO9479S? We have an H270 already in our assembly line and I would very much prefer to use that machine. Is there any solution that would allow me to crimp a right angle QC with strain relief that would allow me to use an automatic crimper? If not, could you please give me some more information on what crimper I can use?
    We do offer the H12 for the SO9405. This is the correct hand tool for this part. The SO9479S does not have a Hollingsworth listed hand tool. They both have dies for the H270 crimp machine. SO9405 uses die set 27056 with a 7/32 wire strip length. SO9479S uses die set 27150 with a 7/32 wire strip length.

  43. Do you by chance have any straight quick connect terminals that have strain relief similar to these right angle ones? I didn’t see any in your catalog but I thought I’d ask.
    We do in fact have the straight version of the terminals mentioned. The 22-18 you will need is our part# SO9605S The 16-14 you will need is our part# SO9705S. Both of these use the H12 as the correct hand tool.
  44. I have been a master electrician for over 36 years. My question concerns crimping of solid wires to female slip-on’s or disconnects such as your terminal SO9600S. My present application concerns 18 AWG solid wire being crimped to a slip-on disconnect such as your SO9600S. I have always been of the opinion that crimping terminals to 12 AWG solid and smaller is not acceptable. I have always refused to do this. I am being told by others that it is allowed by the manufacturer. Do you have data sheets available for your products that address crimping small diameter solid wire. I cannot find such information anywhere except at 3M where they state stranded wire only for their FD18-250 Highland disconnect terminals. You are the experts…I need your help please.
    I agree with you, as far as our products are concerned. The Hollingsworth lines of quick disconnects and tabs are UL listed in our files E70344 Vol. I (listed) and Vol. II (recognized). We rely on UL for test verification and listing service, since most of our products are stand-alone listed crimp terminals and connectors when used with the correct tooling and wire. The disconnects and tabs conform to UL specification 310, and are listed for use with stranded wire only, #22-12 AWG. However, if your application needs to meet UL specifications and will be inspected, the correct crimp tool or machine must be used with our products (that’s probably not the case, since you are referring to non-insulated product). In addition, our terminal line (copper rings, spades, splices, etc) is listed in E31304 and qualifies with either solid or stranded wire, #22-12 AWG.
  45. For part numbers R4086 & R4087 the base material is listed as Copper (non–insulated version), what is the plating material?
    The two parts mentioned below are indeed copper. They have a bright tin plated surface. These are also plated with gold. (Customer requested only).
  46. We have been buying a high temperature ring lug from your company in the past and are afraid we may have the wrong part number. We believe it is R4270S but after checking your catalog and not finding it, I wonder if the real part # could be R42705 or R427OS? I found somewhat close numbers on page 66 of your catalog, if this part is not available could you please provide us with an alternate?
    The R4270S is the correct part number for a 22-16 #4 stud 900° ring terminal. Page 66 in the catalog does show the 900° terminals, but the note that should have gone along with the “*” next to the #10 stud size of the 22 thru 8 wire sizes did not make it. There should be a note advising the customer that other stud sizes besides the 10 are available, and to consult Electro-Term Sales for other options.
  47. I’m looking for a .088/.090 diameter female pin receptacle for 12-14 gauge wire. The drawing I have from our customer has a Lear Corporation (formally Essex International, Inc.) part #471208-AF31. Do you have anything that would be a direct replacement?
    Our technical staff has had no luck in finding an exact match to your part.
  48. Can you please advise us the voltage rate of Nylon insulated (XR5105N) & Vinyl insulated (R4182F) ring tongue terminals?
    The XR5105N is rated for 300 volts and the R4182F for 600 volts. The ratings are a function of the distance from a conducting surface inside the terminal to the end of the insulation at the wire entry, rather than the composition of the insulating material. According to UL, the minimum distance is .032″ for the XR5105N, and .093″ for the R4182F.
  49. We purchase the XS09788 terminal and notice that the label on the bag notes H6EB as the crimping tool. The catalog has H43. Please let me know the correct crimping tool for the XS09788. Also we have a pneumatic crimping tool, Astro 621200, do you have dies available for the XS09788 that could be used in your H59. This of course would be are preferred method of crimping.
    The correct tool for the XSO9788 terminal is the H6EB. We do make a jaw the will fit in our H28 pneumatic cylinder. We do not have anything that would be compatible with your Astro 621200. If you would like to use our tooling, you would need a H28 cylinder and a H28-6EB jaw or the H6EB hand tool.
  50. We just bought 1000ea R4113S on PO 1952132. MY question is, are they ROHS compliant?
    Yes they are. I can have our quality dept send a cert if you would like.
  51. Could you please give me basic concept on how to choose either P4130 or P4130B connector? For example, we use the connector to hold Ni/Cr wire to hook-up wire together, which one is better from electrical/mechanical view?
    The two connectors are virtually the same except for one major difference. The P4130B is a brazed barrel seam which will not open due to a variety of issues, ie, if it happens to be crimped improperly, excessive vibration depending on the application. It also will hold much higher tensile pull strength. The standard P4130 has a non brazed barrel seam that is absolutely fine for most applications. However, once the connector is crimped and depending on the application such as large diesel engines, airframe grounding straps, tanks and other military vehicles, etc. The seams can start to open due to excessive noise and vibration. The majority of our customers use the brazed seam connectors to avoid potential future final assembly issues and failures. When the barrel seam of any terminal manufacturer’s terminals and connectors start to fail, the tensile strength is greatly diminished and failures are inevitable.
  52. We use your Hollingsworth terminal ring tag R4261B on the aircraft windows we manufacture. Can you please tell me the maximum current rating for the R4261B ring or do you have an electrical characteristics data sheet.
    We don’t actually rate our terminals’ current-carrying capacity; that rating is designated more by the capacity and temperature rating of the conductor being used. Here in the states we follow the recommendations of Underwriters Laboratories (UL), which follow assigned maximum ampere ratings designated by the National Electrical Code, and that agency’s ratings are for wire sizes #14 AWG and larger. However, the Assigned Maximum Ampere rating is about 60 to 70 percent of the Static-Heating Test current used by UL, and #16 AWG is tested at 18 amps, so I would recommend a maximum current rating of 12 amps for the R4261B, operating at a temperature of 75°C or less.
  53. Would you please send me the info on R4001BFN and R64641B? I need the W dim for these lugs. Thank you
    The “W” dim for the R4004BFN is .630 + or – .003. The “W” dim for the R64641B is .470 + or -.003.
  54. I cannot find your part number 421-18VN on your website. Can you please tell me what is the modern-day equivalent PN? If there is none, please let me know what is the closest and provide me with a spec of the obsolete part. I will also need the same information for your part number D56-8W. Lastly, I have a Hollingsworth item listed in our computer system as part number R3499B-C. I do see R3499B on your website. Does the “-C” mean anything, or can I consider this a typographical error?
    XSO9624SN is the equivalent to the old ET # 421-18VN. The old ET # D56-8W is an 8 ga ring # 8 stud brazed, which is the description for the HST part # R3499B. The “-C” was a packaging code to indicate 100 pks. It is not part of the number.
  55. Ref.: Terminal lug FIT FLARED construction Hollingsworth pn R3031BF Would you please provide us your customer drawing regarding pn R3031BF? I feel that there is an error in your catalog 2011. It makes reference to insulation diameter to be .265″.- Should it not be 0.315″?
    You are correct, there is an error on page 69 in the catalog. The Insulation Diameter should be .315″/8.00 mm. .
