Product Description
The Simpson 1/4 in. x 2-1/2 in. Mushroom Head Crimp Drive Anchor by Simpson 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 in place upon installation, completely eliminating the need for a secondary tightening procedure. Available in a mushroom head style, this zinc-plated carbon steel anchor is suited for a broad range of fastening tasks including attaching wood or light-gauge steel, securing concrete formwork, and providing overhead support for sprinkler pipes and suspended ceiling panels.
Key Features
- Unique curved shaft design - the preformed curvature acts as a self-contained expansion mechanism, locking the anchor firmly in place for secure, reliable placement without extra steps.
- No secondary tightening required - installation is completed in a single action, saving labor time and reducing the risk of inconsistent fastening on the job site.
- Mushroom head design - delivers a tamper-proof solution that resists unauthorized removal, making it a smart choice for security-sensitive applications such as suspended ceiling panels and overhead sprinkler support.
- Zinc-plated carbon steel construction - provides a level of corrosion resistance appropriate for concrete and grout-filled block environments, supporting long-term holding performance.
- 1/4 in. drill bit compatibility - matches a standard drill bit diameter for straightforward hole preparation, keeping tool requirements simple and installation efficient.
Why This Product
- Faster installation with no tightening step - the curved shaft expansion mechanism does the work automatically, letting crews set anchors quickly and move on without pausing for a secondary tightening procedure.
- Built-in tamper resistance - the mushroom head profile is intentionally designed to deter removal, adding a layer of security for overhead, public-facing, or high-traffic installations.
- Versatile across multiple concrete fastening applications - from attaching concrete formwork to hanging overhead sprinkler pipe support and fastening light-gauge steel, one anchor handles a wide range of common structural tasks in concrete and grout-filled block.
- Trusted Simpson engineering - this anchor carries the design standards Simpson is known for in structural fastening, giving contractors and builders confidence in consistent holding performance on every installation.
