The Simpson CD37112RC Crimp Drive 3/8 in. Zinc-Plated Rod-Coupler Head Anchor is an easy-to-install expansion anchor engineered for use in concrete and grout-filled block. Manufactured by Simpson, this anchor features a preformed curvature along the shaft that creates a built-in expansion mechanism, securing the anchor firmly in place without requiring a secondary tightening procedure. The rod-coupler head style is designed specifically for threaded rod attachments, making this anchor a dependable solution for overhead support applications such as hanging sprinkler pipes and suspended ceiling panels, as well as fastening wood or light-gauge steel to concrete and attaching concrete formwork.

Key Features

• Unique curved shaft design - acts as a built-in expansion mechanism that locks the anchor securely in place upon installation, reducing the risk of loosening over time
• No secondary tightening required - the self-securing shaft speeds up the installation process and eliminates an extra step, saving labor time on the job site
• Rod-coupler head style - purpose-built to accept threaded rod attachments, making it well-suited for overhead support, suspended ceiling installations, and sprinkler pipe hangers
• Zinc-plated carbon steel construction - provides a corrosion-resistant finish that helps maintain anchor integrity in typical concrete and grout-filled block environments
• Compatible with a 1/4 in. drill bit - straightforward hole sizing means less setup time and compatibility with standard drilling equipment

Why This Product

• Faster installs with no extra tightening step - the preformed curved shaft expands and sets during driving, so crews can move through anchor placements more efficiently without stopping to torque each fastener separately
• Versatile across multiple overhead and structural applications - the rod-coupler head design directly supports threaded rod connections needed for sprinkler pipe hangers, suspended ceiling panels, concrete formwork, and wood or light-gauge steel fastening to concrete
• Engineered specifically for concrete and grout-filled block - the expansion anchor design is matched to the base materials where secure, load-bearing connections are most critical, giving contractors confidence in the holding strength
• Available from a trusted manufacturer in the structural fastening industry - Simpson produces the Crimp Drive anchor line with five head style options, so specifying this rod-coupler version fits naturally into a broader fastening system from a single, recognized source
