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.

Custom Low Profile Socket Head Screws - 302 Stainless Steel With 6 Lobe Drive

Custom Low Profile Socket Head Screws - 302 Stainless Steel With 6 Lobe Drive
These custom low profile socket head screws with a  6-lobe (torx) drive were manufactured domestically using 302 stainless steel material with a commercial passivated plain finish.  5,000 pieces of two sizes were produced: M10 - 1.5M X 65MM with a T-45 drive size and M8 - 1.25M X 65MM with a T-30 drive size.  26-30MM of thread was incorporated on the larger version and 22-25MM on the smaller diameter part.  The low profile & 6-lobe drive combination is relatively tricky, especially for these larger diameters as additional controls in tooling are required to avoid flowering on the outside profile of the head.
