Product Description
The Simpson 1/4 in. x 3 in. Zinc-Plated Countersunk Head Crimp Drive Anchor is an easy-to-install expansion anchor engineered for use in concrete and grout-filled block. The preformed curvature along the shaft creates a built-in expansion mechanism that secures the anchor firmly in place, eliminating the need for a secondary tightening procedure and making it well suited for a wide range of fastening tasks - from attaching wood or light-gauge steel to concrete, to installing suspended ceiling panels and hanging overhead support for sprinkler pipes.
Key Features
- Unique curved shaft design - the preformed curvature acts as the expansion mechanism, locking the anchor securely in concrete or grout-filled block without extra steps after installation
- No secondary tightening required - the self-securing expansion action speeds up installation and reduces labor time on the job
- Countersunk head provides a zero-profile solution - the anchor sits flush with or below the fastened surface, keeping finished surfaces clean and unobstructed
- Carbon steel construction with zinc-plated finish - delivers the strength needed for structural fastening applications while the coating provides a layer of corrosion resistance
- Versatile application range - handles fastening wood or light-gauge steel, attaching concrete formwork, and supporting overhead loads such as sprinkler pipes and suspended ceiling panels
Why This Product
- Faster installation without sacrificing holding power - by eliminating the secondary tightening step that traditional expansion anchors require, this crimp drive anchor cuts installation time while the curved shaft ensures a secure, reliable hold in concrete and grout-filled block
- Purpose-built for flush-surface applications - the countersunk head design is ideal for projects where a raised anchor profile would interfere with finishes, panels, or attached materials, making it a practical choice for ceiling and formwork work
- One anchor, multiple job-site uses - from fastening structural wood and light-gauge steel to supporting overhead sprinkler pipe and suspended ceiling systems, this anchor is engineered to cover a broad set of concrete fastening needs
- Trusted Simpson engineering in a zinc-plated carbon steel anchor - the material and finish combination delivers a balance of strength and corrosion resistance suited to the demanding environments where concrete anchoring is typically performed

Frequently Asked Questions
- What substrates is the Simpson CD25300C Crimp Drive anchor designed for?
- The Simpson Strong-Tie Crimp Drive anchor is designed for use in concrete and grout-filled block substrates, making it suitable for a wide range of construction and fastening applications.
- Does this anchor require a secondary tightening step after installation?
- No. The preformed curvature along the shaft creates an expansion mechanism that secures the anchor in place automatically, eliminating the need for any secondary tightening procedure.
- What is the purpose of the countersunk head on the CD25300C?
- The countersunk head provides a zero-profile solution, meaning the anchor sits flush with or below the surface of the material being fastened, which is ideal for applications where a smooth, low-profile finish is required.
- What material and finish is the CD25300C anchor made from?
- The CD25300C is constructed from carbon steel with a zinc-plated finish, providing a balance of strength and corrosion resistance suited for typical indoor concrete fastening applications.
