Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw delivers critical performance advantages in demanding industrial settings where corrosion resistance and mechanical reliability are paramount. The combination of Class 3A UNC coarse thread specification and passivated finish ensures superior thread engagement and protection against chemical exposure, making it ideal for marine equipment, chemical processing machinery, and food processing applications. The fully threaded design maximizes clamping force distribution across the entire 3" length, while the 70,000 psi tensile strength provides exceptional resistance to vibration loosening and mechanical stress. These socket head cap screws solve common fastener failure points in high-moisture, high-temperature environments where ordinary fasteners would rapidly deteriorate.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 3A thread fit for superior tolerance control and UNC coarse threading (5/16"-18) for optimal engagement. The socket head cap screw features a standard head profile with 15/32" diameter and 5/16" head height, driven by a 1/4" hex drive. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmentally responsible manufacturing practices. The right-hand thread direction and fully threaded rod configuration provide consistent performance across industrial applications.
