Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws with 6-32 UNC coarse threads are engineered to solve critical fastening challenges in industrial machinery, automotive assemblies, and precision equipment. The combination of 170,000 psi tensile strength and Rockwell C37 hardness provides exceptional resistance to shear forces and fatigue, while the black-oxide surface treatment offers superior corrosion protection in harsh operating conditions. The hex drive system enables secure installation in tight spaces where traditional fasteners cannot be used, making them ideal for applications requiring high clamping force and vibration resistance. The fully threaded design ensures uniform stress distribution, preventing loosening and maintaining joint integrity in dynamic load environments.
Specification Summary & Compliance
This socket head cap screw features precision 6-32 UNC coarse threads with Class 3A fit for superior dimensional accuracy and engagement. Manufactured to ASTM A574 specifications for alloy steel socket head cap screws, these fasteners maintain strict dimensional tolerances and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
