Professional Applications & Engineering Value
Engineered for demanding industrial applications, these socket head cap screws deliver exceptional performance in heavy machinery, automotive assemblies, and structural frameworks. The zinc-plated alloy steel construction provides superior corrosion resistance while maintaining 170,000 PSI tensile strength under extreme loads. The Class 3A thread fit ensures precise engagement in critical connections, minimizing vibration-induced failures. With their partially threaded design and coarse UNC threads, these fasteners enable rapid installation in time-sensitive production environments while providing reliable clamping force in high-vibration settings. The 1/2" hex drive accommodates standard industrial tools for efficient maintenance and assembly operations.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit and UNC coarse thread specifications (5/8"-11). These socket head cap screws meet ASTM A574 manufacturing requirements for high-strength fasteners. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across global markets. The Rockwell C37 hardness rating and 170,000 PSI tensile strength guarantee consistent performance in the most demanding industrial fastener applications.
