Professional Applications & Engineering Value

These black-oxide steel Phillips flat head tapping screws deliver exceptional performance in sheet metal applications where corrosion resistance and reliable fastening are critical. The thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in high-volume manufacturing. The 82° countersink angle and undercut flat head profile ensure seamless flush mounting that prevents snagging and maintains aerodynamic surfaces in HVAC systems, electronic enclosures, and automotive panels. Engineered specifically for materials up to 0.025" thickness, these No. 8-15 thread forming screws provide superior pull-out resistance and vibration durability, making them ideal for industrial equipment, machinery guards, and metal fabrication projects where joint integrity cannot be compromised.

Specification Summary & Compliance

This No. 8-15 x 3/8" tapping screw features precise thread forming design with 0.164" thread diameter and 15 threads per inch for optimal performance in sheet metal. Manufactured from high-strength steel with black-oxide surface treatment, the screw includes a No. 2 Phillips drive and flat head with undercut profile for secure installation. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use worldwide.
