Professional Applications & Engineering Value
This 1/4"-20 UNC socket head cap screw delivers critical reliability in demanding applications where fastener failure is not an option. The 18-8 stainless steel material provides excellent resistance to oxidation and chemical exposure, making it suitable for machinery, automotive assemblies, and outdoor equipment. The Class 3A thread fit and coarse thread design prevent loosening under vibration while enabling quicker assembly. With its 3/16" hex drive, engineers benefit from high torque application without cam-out, ensuring tight, secure joints in high-stress environments. Fully threaded for maximum grip, these screws are engineered for precision equipment, jigs, and fixtures requiring repeated disassembly and reassembly.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precise dimensional tolerances. The UNC coarse thread (1/4"-20) and right-hand threading adhere to standardized inch fastening systems. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial and export applications.
