Professional Applications & Engineering Value

Engineered for demanding industrial fastening applications, these socket head cap screws deliver critical performance where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition provides excellent durability against chemicals and moisture, while the UNC coarse threads and Class 3A thread fit ensure rapid assembly and reliable clamping force in machinery, equipment frames, and precision assemblies. The hex drive style allows for high-torque installation in confined spaces, reducing installation time and preventing damage to fastener heads. Combined with full threading and wire locking capability, these screws solve common challenges in vibration-prone environments, maintaining joint integrity under dynamic loads and thermal cycling.

Specification Summary & Compliance

This socket head cap screw features precision 8-32 UNC threads with Class 3A fit and coarse thread spacing, manufactured to ASME B18.3 dimensional standards. The fastener maintains strict dimensional tolerances for head diameter (0.27"), length (1/4"), and drive size (9/64"). Compliance is verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries and international markets.
