Custom Stainless Steel Socket Shoulder Bolts

 

Custom Stainless Steel Socket Shoulder Bolt Manufacturers
These custom stainless steel socket shoulder bolts were manufactured using 18-8 stainless steel material with factory passivation finish.  The head was fully cold formed, which took multiple tooling iterations to get just right.  1/4-20 2A thread was rolled at a length of .575" underneath the .305-.311" diameter shoulder.  A .190" across the flats hex socket drive was incorporated at a depth of .120" min.  Certs were made available to our customer's specifications.

Custom 6-Lobe (Torx Alternative) Shoulder Screws in 416 Stainless Steel

 

Custom 6-Lobe (Torx Alternative) Shoulder Screws in Stainless Steel
We had these custom 6-lobe shoulder screws manufactured in 416 stainless steel in the USA for our electronics customer.  DFARS compliant material was used and the parts were heat treated to achieve 26-32 RC.  The 6-lobe drive (T10 size) was made using a combination of broaching and punch, allowing us to bypass cold forming that carries a much longer lead time in our current conditions.  The shoulder measures .13" X .500" in length and the threaded portion is #4-40 with a minimal undercut.  Full certs were included with the parts per our customers requirements.
