Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver critical performance advantages for sheet metal applications where material integrity and joint reliability are paramount. The thread forming technology creates precise, permanent threads in base materials without chip removal, eliminating contamination risks in electrical enclosures, HVAC systems, and automotive assemblies. The combination of fully threaded design and 18 TPI specification ensures maximum thread engagement across the entire fastener length, providing superior pull-out resistance in thin-gauge materials. The Phillips No. 2 drive with pan head configuration offers excellent torque transmission while the zinc plating provides essential corrosion protection for both indoor and outdoor industrial environments.

Specification Summary & Compliance

This No. 6 x 1-1/4" tapping screw features a 0.138" thread diameter with 18 threads per inch and fully threaded construction per standard thread forming specifications. The fastener is manufactured to precise dimensional standards with pan head style (0.27" diameter, 0.097" height) and requires a No. 32 drill bit (0.116" diameter) for proper installation in materials up to 0.025" maximum thickness. Compliance is maintained with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to international safety and substance restriction standards.
