Professional Applications & Engineering Value
This 18-8 stainless steel socket head cap screw delivers critical performance in precision assemblies where corrosion resistance and mechanical reliability are paramount. The Class 3A UNF fine thread ensures tight tolerances for vibration-prone equipment, aerospace components, and automated machinery, preventing loosening under dynamic loads. The combination of 70,000 psi tensile strength and Rockwell B70 hardness provides durability against shear and tensile stresses in heavy-duty industrial applications. The 1/4" hex drive facilitates secure installation in confined spaces, making it ideal for machine tools, automotive subsystems, and high-performance manufacturing equipment requiring repeated maintenance.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision assembly. Features 5/16"-24 UNF fine threads, 1-1/8" fully threaded length, and right-hand thread direction. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
