Professional Applications & Engineering Value
These No. 2 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, vibration-resistant connections. The A/AB tapping screw type with right-hand threading ensures consistent performance in automated assembly processes. The pan head with slotted drive provides excellent torque transmission for secure installations in HVAC systems, electronic enclosures, automotive components, and industrial equipment. The combination of 0.086" thread diameter and 32 TPI precision delivers optimal thread engagement in thin materials, preventing strip-out and maintaining joint integrity under dynamic loads.
Specification Summary & Compliance
These tapping screws feature Class 2A thread tolerances with fully threaded 1/4" length and pointed tip for easy starting. Manufactured to industry standards for A/AB tapping screw types with right-hand thread direction. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance control. Designed for use with No. 48 drill bits (0.076" diameter) in materials up to 0.025" maximum drilling thickness.
