• Versatile application range compatible with standard 1/4" drill bits for efficient installation across various construction substrates

Professional Applications & Engineering Value

Engineered for heavy-duty construction fastening, these zinc-plated steel tapping screws solve critical challenges in concrete, block, and brick applications. The external hex drive provides superior torque transmission, preventing cam-out during installation in dense materials. With right-hand threads and blunt tip design, they create precise mating threads in masonry without pre-tapping, significantly reducing installation time while maintaining 480 lbs shear strength under dynamic loads. The 1-1/4" thread length ensures optimal engagement depth, while the removable feature offers flexibility for structural adjustments - making them ideal for both permanent installations and temporary fixtures in commercial construction projects.

Specification Summary & Compliance

This 1/4" tapping screw features standard inch measurements with right-hand threading and external hex drive configuration. Manufactured from zinc-plated steel with a blunt tip and 1-1/4" length, it requires a 1/4" drill bit for installation with minimum 1" embedment depth. The screw meets industry standards for tapping screw anchors and demonstrates compliance with RoHS 3 (2015/863/EU) environmental regulations, containing no restricted hazardous substances for environmentally conscious construction projects.
