Professional Applications & Engineering Value

These black oxide steel rounded pan head Phillips screws with 1/4"-20 UNC coarse threading deliver exceptional engineering value across industrial applications. The combination of Rockwell B70 hardness and 60,000 psi tensile strength addresses critical failure points in machinery assembly, automotive components, and electrical enclosures where vibration resistance and structural integrity are paramount. The black oxide surface treatment provides essential corrosion protection in humid or chemically aggressive environments, while the fully threaded design ensures maximum engagement in both thin and thick materials. The rounded pan head profile offers a low-profile installation that minimizes protrusion without compromising on the No. 3 Phillips drive torque capacity, making these fasteners ideal for space-constrained assemblies requiring reliable, high-strength connections.

Specification Summary & Compliance

This industrial fastener features precise Class 2A thread fit with UNC coarse threading (1/4"-20) manufactured to exacting ASME B18.6.3 dimensional standards. The inch-system specifications include a 0.492" head diameter with standard pan head profile and right-hand thread direction. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for industrial applications worldwide.
