Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw delivers critical performance advantages in demanding industrial environments where corrosion resistance and mechanical reliability are paramount. The UNC coarse thread configuration with Class 3A precision ensures rapid installation and superior vibration resistance in machinery, manufacturing equipment, and structural assemblies. The passivated finish significantly enhances the natural corrosion resistance of 316 stainless steel, making it ideal for chemical processing, marine applications, and food processing equipment where exposure to corrosive agents is common. The partially threaded design with 1-1/8" thread length provides optimal clamp force concentration while the 1/4" hex drive socket enables high-torque installation in space-constrained applications, reducing assembly time and improving maintenance efficiency.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 3A thread fit per UNC specifications, ensuring consistent engagement and reliable performance. The 5/16"-18 UNC coarse thread with right-hand direction and standard socket head profile meets industrial fastening requirements. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and material safety for global industrial applications.
