Professional Applications & Engineering Value

These blue corrosion-resistant coated steel tapping screws are engineered specifically for demanding concrete, brick, and block applications where durability and reliability are paramount. The Torx drive system eliminates stripping issues common in high-torque installations, while the pointed tip design ensures precise starting and reduced installation effort. The specialized blue corrosion-resistant coating provides critical protection against environmental factors in industrial settings, extending service life and reducing maintenance costs. With tested performance in 3,000 psi concrete, these screws deliver consistent anchoring performance for structural applications, mechanical equipment mounting, and infrastructure projects where vibration resistance and long-term stability are essential.

Specification Summary & Compliance

These 3/16" x 2-3/4" tapping screws feature standard right-hand threads with a 1-5/8" thread length and are manufactured to precise dimensional tolerances. The flat head design with 82° countersink angle ensures proper seating in prepared holes. Installation requires a 5/32" drill bit (0.1563" diameter) with minimum 1" installation depth for optimal performance. All products are RoHS 3 (2015/863/EU) compliant, meeting international environmental and safety standards for industrial components used in construction and manufacturing applications.
