Professional Applications & Engineering Value
These zinc-plated steel tapping screws deliver exceptional value in sheet metal applications where reliable fastening is critical. The thread forming Type B design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The Phillips drive system ensures quick installation with standard tools while minimizing stripping risks. Engineered with a fully threaded blunt tip, these screws distribute clamping force evenly without compromising material structure, making them ideal for industrial assembly lines, HVAC systems, and electronic enclosures where vibration resistance and long-term durability are paramount.
Specification Summary & Compliance
This No. 8-18 x 1/2" tapping screw features precision inch measurements with 0.164" thread diameter and 18 threads per inch specification. The screw is designed for use with No. 29 drill bit (0.136" diameter) and complies with RoHS 3 (2015/863/EU) regulations for restricted substance management. Manufactured to industrial standards for thread forming applications in sheet metal, these screws ensure consistent performance and reliability in professional fastening scenarios.
