Professional Applications & Engineering Value

This 3/8"-16 UNC Class 3A hex headless set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. Manufactured from 18-8 Stainless Steel, it provides excellent corrosion resistance for outdoor equipment, marine components, and food processing machinery. The coarse thread spacing and flat tip design ensure maximum surface contact and prevent loosening under dynamic loads, while the headless configuration allows flush mounting in pulleys, collars, and gears. With Rockwell B80 hardness maintaining structural integrity under torque, this set screw is engineered for precision assembly applications requiring reliable, long-term fastening without maintenance intervention.

Specification Summary & Compliance

This set screw maintains Class 3A thread fit tolerances per UNC standards with 3/8"-16 thread size and 1/4" length. Manufacturing conforms to ASME B18.3 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial applications worldwide.
