Professional Applications & Engineering Value
Engineered for heavy-duty masonry fastening, this 3/8" tapping screw delivers critical performance in concrete, block, and brick applications. The zinc-plated 410 stainless steel construction provides excellent corrosion resistance, while the external hex drive enables high-torque installation without stripping. With 850 lbs shear strength and 490 lbs pull-out resistance tested in 4,000 psi concrete, it solves common anchoring failures in structural applications. The 2 1/4" thread length and blunt tip design ensure secure engagement without compromising material integrity, making it ideal for HVAC, structural framing, and industrial equipment mounting where vibration resistance and removability are essential.
Specification Summary & Compliance
This tapping screw features inch system measurements with 3/8" thread diameter and 2 1/2" length, manufactured to standard right-hand thread specifications. The hex head (9/16" width, 3/8" height) ensures compatibility with standard tools. Meets industry standards for concrete anchor screws with precise Class 2A thread tolerances and complies with RoHS and REACH environmental regulations. Proper installation requires 5/16" drill bit and 1 1/2" minimum depth for optimal performance in masonry substrates.
