Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw delivers critical engineering advantages where corrosion resistance and structural integrity are paramount. Manufactured from premium 316 stainless steel, it effectively resists pitting and crevice corrosion in marine, chemical processing, and food industry applications. The coarse thread design combined with Class 2A thread fit provides excellent engagement in both metallic and non-metallic materials, reducing installation time while maintaining vibration resistance. The 8-inch length with partial threading offers optimal unthreaded shank strength for applications requiring precise clamp load distribution. These industrial hex screws solve common fastener failure points by combining 70,000 psi tensile strength with environmental compliance, making them ideal for structural assemblies, machinery frames, and outdoor infrastructure where long-term reliability is essential.

Specification Summary & Compliance

This hex head screw maintains precise Class 2A thread fit tolerances per UNC standards with 3/8"-16 coarse threading and right-hand direction. Manufacturing conforms to ASME B18.2.1 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility in industrial applications.
