Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw in 316 stainless steel is engineered to address critical industrial challenges where corrosion resistance and structural integrity are paramount. The coarse thread design prevents cross-threading and facilitates quick assembly in wood, metal, and composite materials, reducing installation time in production lines. With a fully threaded 6" length, it provides uniform clamping force across the entire fastener, minimizing stress concentration in applications like machinery frames, structural supports, and marine equipment. The external hex drive enables secure tightening even in confined spaces, while the high tensile strength and Rockwell B70 hardness ensure long-term reliability in dynamic or corrosive environments, making it a cost-effective solution for maintenance and OEM projects.

Specification Summary & Compliance

This hex head screw adheres to precise dimensional standards, including Class 2A thread fit for consistent tolerance and UNC coarse threading per ASME B18.2.1 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use. The manufacturing process meets rigorous quality controls to deliver reliable performance in demanding applications.
