Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel socket head cap screws deliver exceptional performance where corrosion resistance and mechanical reliability are critical. The combination of UNC coarse threads with Class 3A fit ensures precise engagement in machinery, automotive assemblies, and marine equipment, reducing the risk of thread stripping under high vibration conditions. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making these screws ideal for chemical processing, food equipment, and outdoor applications where exposure to moisture and aggressive substances is common. With their 1/4" hex drive and standard socket head profile, they provide excellent torque transmission during installation, minimizing the risk of cam-out and ensuring proper clamping force in critical joints.
Specification Summary & Compliance
This socket head cap screw features 5/16"-18 UNC coarse threads with Class 3A thread fit for precision engagement, manufactured to inch system measurements. The fastener maintains dimensional accuracy with a head diameter of 15/32" and overall length of 1/2". Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety for industrial applications worldwide.
