Professional Applications & Engineering Value

These No. 1 Phillips flat head tapping screws are engineered specifically for sheet metal applications where reliability and efficiency are paramount. The zinc-plated steel construction provides essential corrosion protection in demanding industrial environments, while the thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The precision 48 TPI threading and 82° countersink angle work in concert to create secure, flush-mounted connections that withstand vibration and mechanical stress. Ideal for HVAC systems, electronic enclosures, and automotive components, these A/AB tapping screws deliver consistent performance with their fully threaded design and right-hand thread direction, making them the go-to solution for high-volume manufacturing operations.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread tolerance, these tapping screws feature a 0.073" thread diameter and are designed for use with No. 52 drill bits (0.0635" diameter). The fasteners comply with RoHS 3 (2015/863/EU) environmental regulations and are engineered for sheet metal applications with a maximum drilling thickness of 0.025". The Phillips drive size 0 ensures secure tool engagement during installation, while the standard flat head profile and pointed tip facilitate precise positioning and efficient driving operations.
