Frequently Asked Questions

What base materials is the Simpson Strong-Tie Crimp Drive anchor designed for?

The Crimp Drive anchor is designed for use in concrete and grout-filled block, making it suitable for a wide range of structural and mechanical fastening tasks in masonry construction.

Why does the Crimp Drive anchor not require a secondary tightening procedure?

The anchor features a preformed curvature along its shaft that acts as a built-in expansion mechanism. When driven into the hole, this curved shaft expands against the base material, securing the anchor firmly in place without any additional tightening steps.

What is the advantage of the countersunk head style on the CD18400C?

The countersunk head provides a zero-profile solution, meaning the head sits flush with or below the surface of the fixture material once installed. This is ideal for applications where a smooth, unobstructed surface finish is required.

What material and protective coating does the CD18400C anchor use?

The CD18400C is constructed from carbon steel and features a zinc-plated finish, which provides a layer of corrosion resistance for general-purpose interior anchoring applications in concrete and grout-filled block.
