The Simpson 1/4 in. x 2 in. Countersunk Head Crimp Drive Anchor is an easy-to-install expansion anchor engineered by Simpson for use in concrete and grout-filled block. The preformed curvature along the shaft creates a built-in expansion mechanism that locks the anchor securely in place upon installation, eliminating the need for a secondary tightening procedure. Available in a countersunk head style, this zinc-plated carbon steel anchor is well suited for applications ranging from fastening wood or light-gauge steel to concrete, attaching concrete formwork, and hanging overhead support for sprinkler pipes or suspended ceiling panels.

Key Features

• Unique curved shaft design - the preformed curvature expands against the base material when driven, providing secure, reliable placement in concrete and grout-filled block without extra steps.
• No secondary tightening required - the built-in expansion mechanism locks the anchor in place on installation, significantly reducing labor time on the job site.
• Countersunk head design - sits flush with or below the fixture surface, delivering a zero-profile finish that keeps adjacent materials clear and surfaces clean.
• Zinc-plated carbon steel construction - the zinc plating provides a corrosion-resistant barrier, helping the anchor hold up in demanding concrete fastening environments.

Why This Product

• Faster installation from start to finish - by eliminating the secondary tightening step required by many traditional expansion anchors, the Crimp Drive anchor cuts installation time and keeps projects moving efficiently.
• Versatile across multiple masonry applications - engineered for concrete and grout-filled block, this anchor handles a broad range of tasks including structural wood attachment, formwork, overhead sprinkler pipe support, and suspended ceiling panel installation.
• Flush finish where it matters most - the countersunk head is purpose-built for installations where a protruding fastener head would interfere with materials or compromise a flat surface requirement, making it a practical choice for finish-sensitive work.
• Trusted Simpson engineering - designed and produced by Simpson, a recognized name in structural fastening, giving contractors and builders confidence in the anchor's performance and consistency across repeated use.

Frequently Asked Questions

What base materials is the Simpson Strong-Tie CD25200C Crimp Drive anchor designed for?

The CD25200C Crimp Drive anchor is designed for use in concrete and grout-filled block, making it suitable for a wide range of structural and light-duty fastening applications in masonry substrates.

How does the curved shaft design work to secure the anchor?

The preformed curvature along the shaft acts as a built-in expansion mechanism. When the anchor is driven into the drilled hole, the curved profile expands against the base material, locking the anchor securely in place without requiring any secondary tightening procedure.

Why is the countersunk head beneficial for certain installations?

The countersunk head design sits flush with or below the surface of the fixture being fastened, providing a zero-profile solution. This is ideal for applications where a protruding anchor head would interfere with adjacent materials or where a clean, flat surface finish is required.

What is the CD25200C anchor made of, and does it have any corrosion protection?

The CD25200C is constructed from carbon steel and features a zinc-plated finish, which provides a degree of corrosion resistance suitable for standard interior and protected installations.
