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

Custom 6-Lobe Socket Head Cap Screws - 6-32 X 1-1/4 In 18-8 Stainless Steel Material

Custom 6-lobe socket head cap screws manufactured domestically in 18-8 stainless steel material at approximately 8,000 pcs.  Our customer wanted us to provide these custom screws in black oxide finish after running them through ASTM A967 passivation.  Partial unthreaded shoulder was incorporated and the thread was rolled instead of the cut alternative.  Lead time for similar projects is currently running at 8-12 weeks from order confirmation.
