Professional Applications & Engineering Value

These black-oxide alloy steel socket head cap screws deliver critical performance advantages for industrial equipment, automotive systems, and heavy machinery assemblies. The combination of ASTM A574 specification material and Class 3A UNRC coarse threads provides exceptional fatigue resistance where vibration-induced loosening is a concern. The hex socket drive enables high-torque installation in confined spaces, while the fully threaded design ensures uniform stress distribution across the entire fastener length. Engineered to withstand extreme mechanical stresses, these socket head screws maintain their clamping force integrity even after repeated disassembly and reassembly cycles.

Specification Summary & Compliance

Manufactured to ASTM A574 specifications with Class 3A thread fit tolerance for precision assembly. Features UNRC coarse threads (10-24) with right-hand thread direction and standard socket head profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The inch system measurement ensures compatibility with North American industrial standards and equipment specifications.
