• Durable surface protection through passivation treatment enhancing corrosion resistance without compromising dimensional integrity

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 316 stainless steel rounded head Phillips screws deliver critical corrosion resistance where exposure to chemicals, saltwater, or extreme weather conditions would compromise ordinary fasteners. The UNC coarse threading and Class 2A thread fit provide rapid installation and reliable engagement in various materials, while the passivated finish creates an additional protective oxide layer that significantly extends service life. With full compliance to ASME B18.6.3 standards, these screws offer predictable performance in structural assemblies, machinery manufacturing, marine equipment, and chemical processing systems where fastener failure is not an option. The combination of 80,000 psi tensile strength and Rockwell B85 hardness ensures these fasteners maintain clamping force under vibration and dynamic loads.

Specification Summary & Compliance

This industrial fastener features precision 3/8"-16 UNC coarse threads with Class 2A thread fit tolerances for consistent engagement. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restricted substance compliance for international industrial applications. The passivated finish on 316 stainless steel provides enhanced corrosion protection while maintaining the specified thread geometry and drive characteristics.
