Professional Applications & Engineering Value

This silver corrosion-resistant tapping screw is engineered to address common challenges in construction, such as material degradation and insufficient grip in concrete, brick, and block applications. The steel construction with a protective coating combats moisture and chemical exposure, extending service life in outdoor or high-humidity settings. Its flat head profile and Phillips drive allow for flush mounting and easy torque application, minimizing surface protrusions while ensuring a tight fit. With a pointed tip and right-hand threads, it facilitates quick penetration and secure anchoring, reducing installation time and enhancing structural integrity in heavy-duty projects like framing, fixture mounting, and masonry repairs.

Specification Summary & Compliance

This tapping screw adheres to standard inch measurements, with precise dimensions including a 3/16" screw size, 2 1/4" length, and 0.188" thread diameter. It meets typical thread standards for right-hand direction and is designed for use with a 5/32" drill bit and 82° countersink angle. The product is manufactured to ensure consistent performance, with testing conducted in 3,000 psi concrete and compliance with industry guidelines for pull-out and shear strength. It aligns with general quality and safety expectations for construction fasteners, though specific certifications like RoHS or ASME should be verified per supplier documentation.
