S-92185A637 3/8"-16 x 6" Super-Corrosion-Resistant 316 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads and vibration
• Precision Class 3A thread fit guarantees secure fastening and reduced risk of cross-threading in critical assemblies
• Enhanced durability with Rockwell B70 hardness and passivated finish for extended service life
• Secure hex drive engagement using a standard 5/16" drive, preventing cam-out during high-torque installation
• Optimized partial threading on the 6" length provides unthreaded shank strength where full threads aren't needed
• Full regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These 316 stainless steel socket head cap screws deliver exceptional value in demanding industrial applications where corrosion resistance and mechanical strength are paramount. The passivated finish creates an additional protective oxide layer, significantly enhancing performance in chemical processing, marine equipment, and food processing machinery where exposure to corrosive agents is constant. The Class 3A thread fit and UNC coarse thread profile ensure rapid assembly and superior vibration resistance in heavy machinery, transportation equipment, and structural frameworks. Engineers specify these partially threaded fasteners for applications requiring precise clamp load distribution, utilizing the full 1-1/4" minimum thread length for secure engagement while maintaining shank strength. The combination of 70,000 psi tensile strength and Rockwell B70 hardness provides reliable performance in high-stress applications without compromising corrosion resistance.

Specification Summary & Compliance
