Professional Applications & Engineering Value
These 316 Stainless Steel tapping screws deliver exceptional performance in sheet metal fabrication where corrosion resistance and joint integrity are critical. The thread forming technology eliminates tapping operations by cold-forming mating threads directly into pre-drilled holes, creating superior pull-out strength compared to conventional fastening methods. The fully threaded No. 8 design with 15 TPI ensures maximum engagement in thin materials up to 0.025" thickness, while the Phillips drive system provides familiar, efficient installation across production environments. Ideal for HVAC systems, electronic enclosures, and industrial equipment where vibration resistance and long-term reliability in corrosive conditions are essential requirements.
Specification Summary & Compliance
This thread forming tapping screw features a No. 8 size with 1-1/4" length, 0.164" thread diameter, and standard Class 2A inch thread tolerances. Manufactured to Type A/AB specifications for sheet metal applications with right-hand threading and pointed tip for easy starting. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental responsibility and workplace safety in industrial procurement.
