Custom Automotive Ball Studs - 1215 Steel, Zinc Yellow

 We had 20,000 pieces of these custom automotive ball studs produced in 1215 steel material with heat treat hardening to 25-34 HRC and zinc yellow finish.  The across the flats dimension on this ball stad was relatively large compared with the .25" ball diameter, measuring .437 +/-.01".  Overall length measured .950" with the 1/4-28 thread taking up approximately .423".  

Custom Grade 5 Lug Nuts - 5/16-24 Thread

 

We supplied approximately 21,000 pieces of these custom grade 5 lug nuts to our customer, manufactured using medium carbon steel material with zinc clear finish.  Blue thread lock patch was applied at 360 degrees across the length of internal thread per customer specifications.  An 82 degree angle was maintained at the cone side and .500" width across the flats.  Overall length (height) of the lug nut was also set to .500".  Full certs were available with the parts.

Custom 316 Stainless Steel Button Head Screws - Metric

These custom 316 stainless steel button head screws were manufactured domestically using ASTM A240 spec raw material.  All dimensions and tolerances were to a drawing provided by our customer.  M2.5 X .45 thread was incorporated (cut thread) with thread length set to 8MM.  Head diameter was set to 4.50MM-4.7MM and head height at 1.36MM-1.50MM.  Note that the button head was actually fully machined rather than the typical cold headed operation.  The hex socket drive was broached as a result.  Full certs were provided to our customer per request.

Custom Automotive Ball Studs In Grade 5 Steel With Zinc Yellow Finish

We had 15,000 pieces of these custom automotive ball studs produced in 1215 medium carbon steel material with heat treatment to achieve 25-34 HRC hardness.  10-32 thread (2A fit) was rolled for these parts and the hex was made to .311" across the flats.  Overall length of the part measured .815" and the ball diameter was set to .25".  

Custom 6-Lobe Socket Head Screws - 4140 Alloy Steel Material

These custom 6-lobe socket head screws were manufactured domestically using 4140 alloy steel material with heat treat to 42-47 HRC.  2A 6-48 UNS thread was incorporated with thread length at .375".  T15 6-lobe drive was cold formed and the thread rolled.  This part is almost identical with the .200" length version discussed in an earlier post.  Full certs were provided with the parts per our customer's requirements.  

Custom Lag Thread Bent Anchors - Steel Zinc Material

These custom lag thread bent anchors were manufactured for a woodworking company in Hawaii that required lag screw thread on the long leg and a cosmetically appealing zinc clear finish.  CD-C1018 material was used at a 1/4" in diameter, with a 90 degree bend.  The short leg measured 3/4" in length on the inside and the long leg at 5" overall including the 3/4" of lag screw thread.  All production was done domestically on these parts for the fastest turnaround.

Custom Black Thumb Screws - Knurled 6-32 X 3/8

These custom black thumb screws with diamond knurl were manufactured to our customer's drawing at 2,000 pieces using low carbon steel material with black oxide finish.  The head diameter is set to .313" +/- .005" and the thread length is .375" with the same tolerance.  6-32 thread was rolled rather than cut on these parts.  Full certs were provided with the parts.

Custom 4037 Alloy Steel Flat Socket Head Screws With Cadmium Plating

We had 5,000 pcs of these custom 4037 alloy steel flat socket head screws produced in the USA for our aerospace customer.  ASTM A574 4037 material was used for the production and the cadmium plating was dome per AMS-QQ-P-416A TYpe II, with thickness at 0.0005-.0008".  Heat treat was performed to get the hardness of the parts to Rc 41-45.  The socket drive was cold formed and the thread rolled, both at the same facility.  Full certs were provided with the parts per our customer's requirements.

Custom Torx 6-48 Socket Head Screws - 4140 Alloy Steel Material

These custom torx 6-48 socket head cap screws were manufactured domestically using 4140 alloy steel material with heat treat to 42-47 HRC.  2A 6-48 UNS thread was incorporated with thread length at .200".  T15 6-lobe drive was cold formed and the thread rolled.  Full certs were provided with the parts per our customer's requirements.  

Custom Domestic L Anchor Bolts - ASTM A675 Grade 80

We supplied approximately 450 pieces of these custom domestic L anchor bolts to our construction engineering customer, with full certs.  The parts had to be domestic made using domestic melt material as well in ASTM A675 Grade 80 steel, with plain finish.  1/2-13 thread was incorporated on the 15" long leg, with 13.5" of actual thread - having to cut this length of thread on each piece made the production process significantly slower.  The short leg measured 2".
