Professional Applications & Engineering Value

These No. 6 x 1/2" zinc-plated steel tapping screws deliver exceptional engineering value through their thread forming A/AB type design, which eliminates the need for separate tapping operations in sheet metal applications. The fully threaded configuration with right-hand threading ensures maximum engagement and pull-out resistance, while the Phillips pan head with standard rounded profile facilitates quick installation with common driving tools. The zinc-plated steel construction provides essential corrosion protection for industrial environments, and the precise 18 threads per inch specification guarantees consistent performance in automated assembly processes. These thread forming screws solve critical challenges in metal fabrication by reducing installation time, minimizing component inventory, and providing reliable fastening in thin-gauge materials where traditional threading methods prove inadequate.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread tolerances, these tapping screws feature a 0.138" thread diameter and 1/2" length with fully threaded shank configuration. The A/AB tapping screw type follows industry-standard thread forming specifications for sheet metal applications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence. The screw design accommodates standard No. 32 drill bit (0.116" diameter) preparation with maximum 0.025" drilling thickness capacity for consistent performance across manufacturing applications.
