Professional Applications & Engineering Value

These 6-32 UNC zinc-plated steel rounded head screws deliver exceptional engineering value across industrial fastening applications. The combination of zinc-plated steel and coarse UNC threading provides superior corrosion protection while enabling rapid installation in sheet metal, machinery, and equipment assemblies. The fully threaded design ensures maximum thread engagement in both thin and thick materials, eliminating the need for multiple screw types. With 60,000 psi tensile strength and Rockwell B69 hardness, these rounded head screws maintain clamping force under vibration and thermal cycling, preventing loosening in critical applications. The Phillips No. 2 drive offers familiar, efficient installation while the standard rounded head profile provides a finished appearance without sharp edges, making them ideal for OEM manufacturing, electrical enclosures, and industrial equipment where reliability and compliance are paramount.

Specification Summary & Compliance

These screws feature Class 2A thread fit per UNC standards with precise dimensional accuracy. Manufacturing complies with ASME B18.6.3 specifications for consistent quality and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, ensuring suitability for global industrial markets. The inch system measurements maintain 7/8" length with 0.138" thread diameter and standard rounded head profile for uniform installation characteristics.
