Professional Applications & Engineering Value

These zinc-plated steel screws with Phillips pan head design address common industrial challenges where corrosion resistance and consistent fastening performance are critical. The fully threaded UNC coarse pattern ensures rapid assembly in production lines while maintaining strong grip in metal, plastic, and composite materials. With 60,000 psi tensile strength and Rockwell B70 hardness, they prevent stripping and deformation under vibration or thermal cycling in machinery, electrical enclosures, and automotive components. The Class 2A thread fit provides reliable interchangeability with standard components, reducing installation errors and maintenance downtime in industrial fastening applications.

Specification Summary & Compliance

This screw features precision UNC coarse threads with Class 2A tolerance for consistent fit, manufactured to ASME B18.6.3 specifications. It maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use.
