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".

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.
