Professional Applications & Engineering Value
Engineered for demanding industrial fastening, these 10-24 UNC coarse thread screws solve critical vibration loosening and corrosion challenges in machinery assembly, electrical enclosures, and structural frameworks. The zinc-plated steel construction provides sacrificial protection against oxidation while maintaining 60,000 psi tensile strength for high-stress connections. Partially threaded design enables precise clamp force distribution, preventing joint failure in stacked components. With ASME B18.6.3 compliance ensuring dimensional consistency, these rounded head screws deliver reliable performance in automotive, manufacturing, and infrastructure projects where fastener integrity directly impacts operational safety.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerances with UNC coarse threading (10-24 size) and 2-1/4" length. Full compliance with ASME B18.6.3 mechanical specifications, RoHS 3 (2015/863/EU) hazardous substance restrictions, and REACH (EC 1907/2006) chemical safety requirements. Threading covers 1-1/2" minimum thread length with right-hand direction for standard assembly practices.
