Professional Applications & Engineering Value
Engineered for demanding industrial environments, these Phillips truss head screws deliver critical performance advantages. The passivated 18-8 stainless steel construction provides excellent corrosion resistance, making them ideal for outdoor equipment, marine hardware, and chemical processing applications where moisture and corrosive agents are present. The wide truss head distributes clamping force over a larger surface area, preventing material distortion in sheet metal, plastics, and electronic enclosures. With fully threaded UNC coarse spacing and Class 2A fit, these screws offer rapid installation and reliable vibration resistance in assembly lines, machinery, and automotive components. Their 70,000 psi tensile strength ensures structural integrity under dynamic loads, while compliance with ASME B18.6.3 guarantees dimensional consistency for replacement and maintenance operations.
Specification Summary & Compliance
This screw features precise Class 2A thread fit with UNC coarse thread spacing (6-32 size) and full threading along its 1-1/2" length. Manufacturing adheres to ASME B18.6.3 specifications for dimensional accuracy. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance control.
