Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw delivers exceptional engineering value in demanding applications where corrosion resistance and structural integrity are paramount. The 316 stainless steel composition provides superior protection against chemical exposure and atmospheric corrosion, making it ideal for marine, chemical processing, and food industry equipment. The partially threaded design with coarse UNC threading ensures rapid assembly while maintaining strong clamping force across the 9" length. With external hex drive configuration, installers benefit from high torque application capability without slippage, significantly reducing installation time in structural frameworks, machinery assembly, and heavy equipment manufacturing. The combination of 70,000 psi tensile strength and precise Class 2A thread fit guarantees reliable performance in vibration-prone environments, preventing loosening and maintaining joint integrity over extended service life.

Specification Summary & Compliance

This industrial fastener features precise Class 2A thread fit with 3/8"-16 UNC coarse threads and maintains dimensional compliance with ASME B18.2.1 specifications. The manufacturing process ensures consistent thread diameter of 0.375" with minimum thread length of 1 1/4" on the 9" overall length. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, confirming environmental safety and restricted substance adherence for global industrial applications.
