Professional Applications & Engineering Value
Engineered for high-performance industrial applications, these socket head cap screws deliver exceptional reliability in machinery, automotive, and heavy equipment assemblies. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the 170,000 psi tensile strength required for critical structural connections. The Class 3A UNRF fine threads ensure precise engagement in tapped holes, reducing the risk of vibration-induced loosening in dynamic environments. With their fully threaded design and 5/16" hex drive, these fasteners enable efficient installation in confined spaces while providing consistent clamping force across the entire 3" length, making them ideal for demanding applications where reliability and precision are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with ASTM A574 material standards, these socket head cap screws feature Class 3A thread fit for precision applications. The 3/8"-24 UNRF fine thread configuration ensures optimal performance in high-vibration environments. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory adherence for global industrial applications.
