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.
