Professional Applications & Engineering Value
These thread forming tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The black-oxide steel construction provides essential corrosion protection while maintaining the mechanical strength needed for industrial environments. The No. 6-18 thread form and pointed tip design enable easy starting and smooth installation without pre-tapping, significantly reducing assembly time and labor costs. The Phillips drive system ensures consistent torque application and minimizes tool slippage, while the fully threaded configuration maximizes pull-out resistance in thin materials. These tapping screws are ideal for HVAC systems, electrical enclosures, automotive components, and construction applications where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
These precision thread forming screws feature a 0.138" thread diameter with 18 threads per inch and 1-1/2" length, manufactured to standard A/AB tapping screw specifications. The Class 2A thread tolerance ensures consistent performance and interchangeability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and global market acceptance. Designed for use with No. 32 drill bit (0.116" diameter), these screws are optimized for 0.025" maximum drilling thickness in sheet metal applications.
