Professional Applications & Engineering Value

These Type B thread forming screws deliver exceptional value in sheet metal fabrication and industrial assembly applications. The zinc-plated steel construction provides reliable corrosion resistance while the specialized thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The Phillips drive system ensures consistent torque application, while the fully threaded 0.112" diameter shank with 24 threads per inch creates secure, vibration-resistant connections. Engineered specifically for compatibility with No. 44 drill bits, these tapping screws streamline the assembly process in HVAC systems, electrical enclosures, and machinery panels where reliable fastening in thin materials is critical.

Specification Summary & Compliance

This No. 4-24 x 1/4" tapping screw features precision right-hand threads with standard thread forming tolerances, fully threaded blunt tip configuration, and pan head design with 0.219" diameter. Manufactured to industry standards for thread forming Type B screws and certified RoHS 3 (2015/863/EU) Compliant for environmental safety. The specified No. 44 drill bit compatibility (0.086" diameter) ensures proper hole preparation and optimal thread engagement in sheet metal applications.
