Professional Applications & Engineering Value
These 316 Stainless Steel Socket Head Cap Screws deliver critical performance advantages in corrosive and high-stress environments where fastener failure is not an option. The combination of UNF fine threading with Class 3A precision fit addresses vibration-induced loosening in machinery, automotive, and marine equipment, while the passivated finish significantly enhances corrosion resistance beyond standard stainless steel. The hex drive socket head design allows for high-torque installation in confined spaces, making these fasteners ideal for precision assembly applications requiring both chemical resistance and mechanical reliability. Engineered for critical joints in chemical processing equipment, offshore platforms, and food processing machinery where exposure to aggressive media demands superior material performance.
Specification Summary & Compliance
This 1/4"-28 UNF Socket Head Cap Screw features precise Class 3A thread fit per UNF standards with full threading along the 1 1/8" length. Manufactured from 316 Stainless Steel with Rockwell B70 hardness and 70,000 psi tensile strength, the fastener includes a passivated surface treatment for enhanced corrosion protection. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and restricted substance management throughout the manufacturing process.
