Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws solve critical fastening challenges in sheet metal assemblies where corrosion resistance and joint integrity are paramount. The thread forming design eliminates the need for separate tapping operations by cold-forming mating threads directly into the base material, creating stronger connections than conventional cutting screws. The slotted pan head configuration combines installation accessibility with a finished appearance, while the fully threaded shank maximizes engagement in thin materials. Engineered specifically for 0.025" maximum material thickness, these A/AB type tapping screws prevent stripping and maintain clamp force under vibration, making them ideal for electrical enclosures, HVAC systems, and industrial equipment where reliable fastening is non-negotiable.

Specification Summary & Compliance

This No. 10-12 x 1/2" tapping screw features precise 0.19" thread diameter with 12 threads per inch and Class 2A thread tolerances for consistent performance. The slotted pan head measures 0.373" in diameter with 0.11" height for standardized installation. Manufactured to thread forming standards for sheet metal applications using No. 21 drill bit (0.159" diameter) preparation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability.
