Professional Applications & Engineering Value
Engineered for precision industrial fastening applications, these socket head cap screws deliver exceptional performance in machinery, automotive, and aerospace assemblies where reliability is critical. The zinc-plated alloy steel construction provides superior corrosion protection while maintaining the 170,000 PSI tensile strength needed for high-load applications. The fine UNF threads with Class 3A fit ensure precise engagement in tapped holes, minimizing backlash and maintaining alignment in precision equipment. The combination of Rockwell C37 hardness and fully threaded design prevents thread deformation during installation and allows for uniform stress distribution, solving common issues of joint loosening and premature failure in vibrating environments.
Specification Summary & Compliance
This 3/8"-24 UNF socket head cap screw features precision Class 3A thread fit with right-hand fine threading and full thread coverage. Manufactured to ASTM A574 specifications, the fastener meets rigorous quality standards for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for international manufacturing applications requiring strict material composition controls.
