Professional Applications & Engineering Value

These black-oxide alloy steel socket head cap screws deliver critical performance advantages in industrial settings where vibration resistance and structural integrity are paramount. The Torx Plus IP30 drive system addresses common installation challenges by providing superior torque transfer while reducing fastener damage during high-torque applications. Engineered with UNC coarse threads and Class 3A fit, these fasteners ensure precise alignment and reliable clamping force in machinery, automotive assemblies, and heavy equipment. The combination of 180,000 psi tensile strength and Rockwell C39 hardness makes these screws ideal for applications requiring repeated disassembly and reassembly without performance degradation. The fully threaded design maximizes contact surface area, distributing load more effectively across joined components in structural frameworks and precision equipment.

Specification Summary & Compliance

This 1/4"-20 UNC socket head cap screw features precision Class 3A thread fit with coarse thread spacing and right-hand thread direction. Manufactured to ASTM A574 specifications for consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The black-oxide surface treatment provides additional corrosion protection while maintaining dimensional stability across the 1 1/4" length and 3/8" head diameter.
