Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal applications where traditional fastening methods fall short. The thread-forming A/AB tapping screw design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The Phillips/Slotted drive combination provides installation flexibility across different work environments, while the fully threaded configuration ensures maximum holding power across the entire 2" length. The pointed tip facilitates precise starting and alignment, minimizing installation errors in thin-gauge materials. These industrial screws are engineered to solve common sheet metal fastening challenges including strip-out prevention, corrosion resistance, and consistent clamping force distribution.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.164" thread diameter and 15 threads per inch for consistent performance in sheet metal assemblies. The thread forming tapping method creates permanent, high-strength connections without requiring pre-tapped holes. These No. 8 x 2" screws feature Class 2A thread tolerances and are engineered for use with No. 29 drill bits (0.136" diameter) in materials up to 0.025" thickness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications worldwide.
