Professional Applications & Engineering Value

These thread forming sheet metal screws deliver exceptional performance in metal fabrication and assembly operations. The zinc-plated steel construction provides reliable corrosion protection while maintaining high tensile strength for demanding applications. The A/AB tapping screw design with 18 threads per inch creates precise, durable threads in sheet metal up to 0.025" thickness, eliminating the need for separate tapping operations and reducing assembly time. The Phillips pan head configuration offers excellent drive transfer and a clean finished appearance, making these No. 6 x 1-1/2" fasteners ideal for HVAC systems, electronic enclosures, automotive components, and construction projects where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These thread forming screws feature a 0.138" thread diameter with standard right-hand threading and are designed for use with No. 32 drill bits (0.116" diameter). Manufactured to precise dimensional standards with fully threaded configuration and Class 2A thread fit for consistent performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
