Professional Applications & Engineering Value
These Black-Oxide Steel thread forming screws are specifically engineered for sheet metal applications where reliability and durability are paramount. The A/AB tapping screw type with pointed tip and thread forming action eliminates the need for separate tapping operations, reducing assembly time and labor costs. The Phillips pan head design provides excellent drive stability while maintaining a low profile for clearance-critical installations. With a maximum drilling thickness of 0.025", these No. 8 tapping screws deliver consistent performance in HVAC systems, electronic enclosures, automotive components, and industrial equipment where vibration resistance and long-term fastening integrity are essential.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.164" thread diameter and 15 threads per inch specification. Features fully threaded design with standard pan head profile (0.322" head diameter) and No. 2 Phillips drive compatibility. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. Recommended for use with No. 29 drill bit (0.136" diameter) for optimal performance in sheet metal applications up to 0.025" thickness.
