Professional Applications & Engineering Value

This 316 stainless steel rounded truss head screw delivers exceptional engineering value in demanding environments where corrosion resistance and structural integrity are critical. The passivated finish enhances the natural corrosion-resistant properties of 316 stainless steel, making it ideal for marine, chemical processing, and food processing equipment where exposure to moisture and chemicals is constant. The wide truss head design distributes clamping force over a larger surface area, preventing surface damage to softer materials while providing superior resistance to loosening from vibration. With fully threaded UNC coarse spacing and Class 2A thread fit, these screws offer quick installation and reliable performance in assembly lines, machinery, and structural applications where time efficiency and durability are paramount.

Specification Summary & Compliance

This fastener features precision 5/16"-18 UNC coarse threads with Class 2A fit tolerance ensuring consistent thread engagement. Manufactured to ASME B18.6.3 specifications for dimensional accuracy and performance standards. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits.
