• Optimized for thin materials with a maximum drilling thickness of 0.025", perfect for standard sheet metal applications
• Reliable drive engagement using a No. 2 Phillips drive, minimizing cam-out and ensuring consistent fastening torque
• Full thread engagement along the 2" length provides maximum grip and vibration resistance in assembled components
• Environmental compliance meets RoHS 3 and REACH standards, ensuring safe use in regulated industries

Professional Applications & Engineering Value

This No. 8 x 2" Phillips Truss Head Tapping Screw is engineered to address common challenges in sheet metal fastening, where material thinness and corrosion are critical concerns. The 18-8 Stainless Steel material offers excellent resistance to rust and oxidation, making it suitable for outdoor, marine, or high-humidity industrial settings. Its thread forming design eliminates the need for separate tapping operations, reducing assembly steps and potential errors. The wide truss head distributes clamping force over a larger area, preventing deformation in delicate sheet metal panels and maintaining structural integrity. With a pointed tip and fully threaded shank, it ensures quick starts and secure holds in applications ranging from HVAC ductwork to electronic enclosures and automotive panels.

Specification Summary & Compliance

This screw features a thread diameter of 0.164" with approximately 15 threads per inch (TPI), designed for thread forming in accordance with Type A/AB standards. It is compatible with a No. 29 drill bit (0.136" diameter) for optimal performance in materials up to 0.025" thickness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it meets stringent international safety and sustainability requirements for industrial components.
