Professional Applications & Engineering Value

This heavy-duty tapping screw delivers critical performance where structural integrity matters most. The zinc-plated steel construction provides essential corrosion protection for long-term reliability in concrete, block, and brick applications. Engineered with an external hex drive and optimized thread length, it ensures rapid installation and superior holding power while addressing common challenges of masonry fastening - including material spalling and insufficient grip. The removable design offers maintenance flexibility without compromising the anchor point integrity, making it ideal for both permanent installations and applications requiring future access. Tested in 4,000 psi concrete, this screw provides predictable performance for contractors and engineers who demand consistent results in demanding construction environments.

Specification Summary & Compliance

Manufactured to inch system standards with precise 1/4" thread diameter and 3" overall length. Features right-hand threading with Class 2A tolerance for reliable engagement. The blunt tip design ensures proper seating in pre-drilled 1/4" holes with minimum 1" installation depth requirement. Compliant with RoHS 3 (2015/863/EU) regulations, ensuring environmental responsibility while maintaining the mechanical properties required for heavy-duty anchoring applications in concrete, block, and brick substrates.
