• Optimized for high-strength concrete, having been tested and proven in 4,000 psi concrete for guaranteed performance in block, brick, and concrete substrates.
• Easy and secure installation with an external hex drive and 3/4" head width, allowing for high torque application and reducing the risk of tool slippage.
• Deep, effective thread engagement from a 2 3/4" thread length and a 3" overall length, providing maximum holding power and stability.
• Removable design offers flexibility for adjustments or disassembly without compromising the integrity of the base material.
• Compliance with environmental standards as a RoHS 3 (2015/863/EU) compliant product, meeting strict regulatory requirements for hazardous substances.

Professional Applications & Engineering Value

This heavy-duty tapping screw is engineered to solve critical fastening challenges in concrete, block, and brick. The zinc-plated steel material provides excellent resistance to corrosion, which is essential for both indoor and outdoor structural applications. The external hex drive and robust hex head design enable high-torque installation, ensuring the screw is seated securely without stripping. This is particularly valuable in high-vibration environments or where shear strength is a primary concern, such as securing machinery, structural frames, and safety barriers. The right-hand thread and blunt tip facilitate easy starting and precise placement, reducing installation time and labor costs while delivering a reliable, removable anchor solution tested in 4,000 psi concrete.

Specification Summary & Compliance

This screw features a 1/2" thread diameter and a 3" length with a 2 3/4" thread length, designed as a tapping screw for creating its own thread in pre-drilled holes. The installation requires a 7/16" drill bit with a 2 1/2" minimum installation depth. It conforms to typical inch-series tolerances for such fasteners and is verified as RoHS 3 (2015/863/EU) Compliant, ensuring it is free from specific hazardous substances as per the directive.
