Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for sheet metal applications where reliability and installation efficiency are critical. The thread forming technology creates strong, permanent threads in pre-drilled holes without requiring additional tapping operations, significantly reducing assembly time and eliminating the risk of cross-threading. The Phillips flat head design with 82° countersink angle ensures a flush finish that minimizes protrusion and maintains aerodynamic surfaces in metal enclosures, HVAC systems, and electronic chassis. The combination of fully threaded shanks and right-hand threading provides exceptional pull-out resistance while the pointed tip facilitates precise alignment during installation. These A/AB tapping screws are ideal for high-volume manufacturing environments where consistent performance and regulatory compliance are mandatory.

Specification Summary & Compliance

These No. 6 x 1-3/4" tapping screws feature precision thread forming technology with a 0.138" thread diameter and 18 threads per inch, designed for use with No. 32 drill bits (0.116" diameter). The flat head profile incorporates an 82° countersink angle for optimal flush mounting in sheet metal up to 0.025" thickness. Manufactured to A/AB tapping screw standards with right-hand threading and fully threaded shanks, these fasteners comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial safety and substance restriction requirements.
