Professional Applications & Engineering Value

These 316 stainless steel socket head cap screws deliver critical performance advantages in demanding industrial settings where corrosion resistance and mechanical reliability are paramount. The combination of UNF fine threading and Class 3A precision provides superior vibration resistance in machinery, automotive, and marine applications. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making these fasteners ideal for chemical processing equipment, offshore installations, and food processing machinery where exposure to aggressive media is common. With their 3/8" hex drive and standardized socket head profile, these screws enable efficient installation in confined spaces while maintaining high torque transmission capabilities.

Specification Summary & Compliance

This 7/16-20 UNF socket head cap screw features precise Class 3A thread fit according to Unified Thread Standard specifications, ensuring consistent engagement and reliable clamping force. The 3" length with 1-3/8" minimum thread length provides optimal fastening depth for various material thicknesses. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances. The right-hand thread direction and partial threading configuration meet industry standards for heavy-duty mechanical applications requiring precise axial positioning and secure fastening.
