Professional Applications & Engineering Value
These No. 6 x 3/8" zinc-plated steel tapping screws deliver exceptional performance in sheet metal assembly where vibration resistance and pull-out strength are critical. The thread forming technology creates permanent, high-strength threads in parent material without generating chips, eliminating secondary tapping operations and reducing assembly costs. The Phillips flat head design with 82° countersink provides a secure, flush finish that prevents snagging while the fully threaded configuration ensures maximum grip length. Manufactured from zinc-plated steel, these screws offer reliable corrosion protection for HVAC systems, electrical enclosures, and industrial equipment where metal-to-metal fastening is required.
Specification Summary & Compliance
These thread forming tapping screws feature right-hand threads with Class 2A fit tolerances and comply with A/AB type standards. The 0.138" thread diameter with 18 threads per inch ensures precise engagement while the specified No. 32 drill bit (0.116" diameter) provides optimal hole preparation. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming they're free from restricted substances for industrial use.
