Professional Applications & Engineering Value

These blue corrosion-resistant coated steel tapping screws are engineered to address common challenges in industrial fastening, such as material degradation and installation inefficiency. The Torx drive minimizes tool slippage, enabling higher torque application without stripping, which is critical for time-sensitive projects. The pointed tip facilitates quick starts in dense materials like concrete, brick, and block, reducing labor and preventing misalignment. With a flat head design that countersinks neatly, these screws provide a flush surface, enhancing safety and aesthetics in structural applications. Ideal for heavy-duty scenarios, they ensure reliable performance where vibration and load stresses are prevalent, supported by tested strength metrics that prevent failure in high-pressure environments.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 1/4" and length of 2-3/4", featuring a right-hand thread direction and pointed tip for optimal engagement. It is designed for use with a 3/16" drill bit and an 82° countersink angle, ensuring precise installation depths starting from 1 inch. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming adherence to environmental and safety standards for industrial fasteners.
