Professional Applications & Engineering Value

These 410 stainless steel tapping screws are specifically engineered for sheet metal applications where corrosion resistance and reliable fastening are critical. The thread forming Type B design creates strong, permanent threads in base materials without generating chips, eliminating contamination concerns in sensitive assemblies. The fully threaded construction with 18 TPI provides consistent clamping force along the entire engagement length, preventing loosening under vibration. The Phillips pan head configuration ensures flush mounting while the blunt tip facilitates proper alignment during installation. These industrial fasteners solve common challenges in metal fabrication, HVAC systems, and electronic enclosures by combining corrosion-resistant properties with efficient installation using standard No. 29 drill bits.

Specification Summary & Compliance

This No. 8 x 1/2" tapping screw features a 0.164" thread diameter with 18 threads per inch in right-hand direction. The pan head measures 0.322" in diameter with 0.115" height, designed for Phillips No. 2 drive compatibility. Manufactured to thread forming Type B specifications for sheet metal applications, these screws require No. 29 drill bit (0.136" diameter) for proper hole preparation. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to international standards for industrial fasteners.
