Professional Applications & Engineering Value
Engineered for industrial fastening where reliability is critical, these socket head cap screws excel in machinery, automotive, and heavy equipment applications. The black-oxide alloy steel construction combats rust and wear, while the Class 3A UNC coarse thread maintains secure connections despite vibrations. With a Rockwell C37 hardness and 170,000 PSI tensile strength, they prevent stripping and deformation under load, solving common failure points in high-stress assemblies. The hex drive socket facilitates easy access in tight spaces, streamlining maintenance and reducing downtime.
Specification Summary & Compliance
This screw adheres to ASTM A574 specifications, ensuring consistent quality and performance. Threading conforms to UNC coarse standards with Class 3A fit for precise tolerance. Dimensions include a 7/16"-14 thread size, 1 3/4" length, and 3/8" hex drive. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting environmental and safety requirements for industrial use.
