Professional Applications & Engineering Value

These No. 1 zinc-plated steel tapping screws deliver exceptional performance in sheet metal assembly applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the risk of loose metal chips contaminating sensitive equipment while creating stronger thread engagement than conventional cutting screws. The pan head design with Phillips drive provides reliable countersinking and consistent torque transmission, preventing head stripping during high-volume production. Engineered for industrial fastening in HVAC systems, electrical enclosures, and automotive components, these fully threaded screws maintain structural integrity under dynamic loads while the zinc plating offers essential corrosion protection in demanding environments.

Specification Summary & Compliance

These thread forming tapping screws feature precision right-hand threads with 48 TPI configuration and comply with A/AB tapping screw standards. The 1/4" length and 0.073" thread diameter provide optimal fastening dimensions for sheet metal applications requiring No. 52 drill bit preparation (0.0635" diameter). Manufacturing adheres to RoHS 3 (2015/863/EU) compliance, ensuring environmental responsibility while maintaining the mechanical properties necessary for reliable industrial performance. The combination of zinc-plated steel construction and thread forming technology delivers consistent results across high-volume assembly operations.
