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 Oval Point Set Screws - Metric

 

We had 18,000 pieces of these metric custom oval point set screws manufactured for our renewable energy customer in the United Kingdom.  304 stainless steel material was used and all production was done domestically in the USA.  Overall length was set to .384-.404 inches and the oval point was done with a .120 radius.  4MM x 0.7 thread was cut with 6g thread fit and a .0795-.0805" hex socket drive was broached.  Lead time for production was approximately 10 weeks.
