• Comprehensive regulatory compliance including ASME B18.6.3, RoHS 3, and REACH ensures material safety and quality consistency

Professional Applications & Engineering Value

These 10-32 UNF zinc-plated steel rounded head screws address critical industrial fastening challenges where corrosion resistance and mechanical reliability are paramount. The fine thread spacing combined with Class 2A thread fit provides exceptional vibration resistance in machinery, automotive assemblies, and electrical enclosures subject to constant movement. The zinc-plated steel construction offers superior protection against oxidation and chemical exposure, while the partially threaded configuration enables precise clamping control in multi-material assemblies. With 60,000 psi tensile strength and Rockwell B69 hardness, these fasteners maintain structural integrity in high-stress applications, making them ideal for manufacturing equipment, transportation systems, and heavy-duty industrial frameworks requiring long-term, maintenance-free performance.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerances ensuring dimensional precision and interchangeability. The 10-32 UNF fine thread configuration maintains consistent pitch accuracy, while the 3" length with 1½" minimum thread length provides optimal engagement depth. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance control, meeting global industrial standards for quality-assured fastening solutions.
