At Stafford Manufacturing Corp., we use only high grade materials and premium quality hardware in our shaft collars and rigid couplings. Socket set screws and socket head cap screws are either made of heat treated alloy steel, or 18-8 austenitic stainless steel, depending on the application and customer preference.

All hardware we use meets applicable ASA/ASME/ANSI B18.3 standards, which precisely outline quality specifications for socket cap, shoulder, and set screws. Because the hardware used in our shaft collars and rigid couplings has a significant impact on the part’s performance, we carefully screen all raw material and hardware suppliers to ensure we are using the highest grade materials.
