Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 8-32 UNC coarse thread pan head screws deliver exceptional performance where reliability matters most. The black oxide steel construction provides superior corrosion resistance, extending service life in manufacturing equipment, machinery assemblies, and electronic enclosures. The fully threaded design ensures maximum thread engagement along the entire 5/8" length, distributing clamping force evenly to prevent joint failure. The No. 2 Phillips drive offers efficient installation with reduced tool slippage, while the rounded pan head profile provides a low-profile finish that minimizes snagging in confined spaces. These screws solve critical fastening challenges by combining 60,000 psi tensile strength with precise Class 2A thread fit, making them ideal for applications requiring repeated disassembly and reassembly without compromising thread integrity.

Specification Summary & Compliance

This 8-32 UNC pan head Phillips screw features precise Class 2A thread fit with coarse thread spacing, manufactured to exacting ASME B18.6.3 standards. The product maintains dimensional accuracy with 0.164" thread diameter and 5/8" length, ensuring consistent performance across industrial applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility, while the mechanical properties including Rockwell B70 hardness and 60,000 psi tensile strength guarantee reliable performance in demanding fastening scenarios.
