Professional Applications & Engineering Value

This 316 stainless steel set screw delivers critical performance where corrosion resistance and precision threading are paramount. The hex headless design with 5/32" drive enables flush mounting in confined spaces while maintaining high torque capability. UNC coarse threads with Class 3A fit provide superior engagement in soft metals and plastics, preventing loosening in vibrating equipment. The cup tip concentrates clamping force for secure shaft positioning in pulleys, gears, and collars. Engineered for industrial applications requiring chemical resistance and dimensional stability, from food processing machinery to marine hardware and chemical plant equipment.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with UNC 5/16"-18 coarse threads and Class 3A thread fit for precision tolerance. The 3/8" length and 0.313" thread diameter maintain dimensional accuracy across production lots. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety in industrial supply chains.
