Professional Applications & Engineering Value

This 6-32 x 3/8" rounded truss head screw is engineered to address common industrial challenges such as vibration loosening and material fatigue. The Black-Oxide finish on 18-8 stainless steel provides enhanced corrosion protection, making it suitable for outdoor equipment, automotive assemblies, and electronic enclosures exposed to moisture. Its wide truss head distributes pressure evenly, preventing damage to soft surfaces while the fully threaded UNC coarse design ensures quick installation and strong holding power in plastics or sheet metal. With a Phillips drive, it offers efficient torque transfer, reducing assembly time and improving workflow in high-volume production environments.

Specification Summary & Compliance

The screw features precise Class 2A thread fit and UNC coarse thread spacing for reliable performance. It meets ASME B18.6.3 specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are adhered to in industrial applications.
