Professional Applications & Engineering Value

This 410 stainless steel tapping screw delivers critical engineering advantages for concrete, block, and brick applications where corrosion resistance and structural integrity are paramount. The external hex drive design provides superior torque transmission during installation, preventing cam-out and ensuring proper seating in masonry substrates. With 190 lbs pull-out strength and 225 lbs shear capacity tested in 3,000 psi concrete, this heavy-duty tapping screw addresses the common failure points of inferior anchors in construction and industrial settings. The combination of right-hand thread configuration and pointed tip facilitates smooth penetration while the removable feature offers flexibility for temporary installations or future modifications.

Specification Summary & Compliance

This 1/4" x 5" hex head tapping screw features inch system measurements with precise thread dimensions (0.25" diameter, 2 1/4" thread length) and right-hand thread direction conforming to industry standards. The anchor screw is engineered for use with 3/16" drill bits (0.1875" diameter) and requires minimum 1" installation depth for optimal performance. Manufactured from 410 stainless steel with hex head configuration (5/16" width, 0.18" height) and 0.414" flange diameter, this tapping screw anchor meets rigorous performance requirements for construction applications and complies with relevant industry specifications for masonry anchoring systems.
