The Simpson Crimp Drive 3/16 in. x 1 1/4 in. Zinc-Plated Mushroom Head Anchor is a fast, reliable expansion anchor engineered for use in concrete and grout-filled block. The preformed curvature along the shaft acts as a built-in expansion mechanism that locks the anchor securely in place upon installation, removing the need for a secondary tightening procedure. Available in a mushroom head style, this zinc-plated carbon steel anchor is well suited for fastening wood or light-gauge steel, attaching concrete formwork, and supporting overhead installations such as sprinkler pipes and suspended ceiling panels.

Key Features

• Unique curved shaft design - the preformed curvature creates a self-locking expansion mechanism, so the anchor holds firmly in concrete and grout-filled block without any secondary adjustment.
• No secondary tightening required - once driven, the anchor is set, reducing installation steps and speeding up the overall workflow on any project.
• Mushroom head style - the low-profile, tamper-proof head resists removal after installation, making it a dependable choice for fastening wood or light-gauge steel in high-traffic or secured areas.
• Zinc-plated carbon steel construction - the zinc plating provides a layer of corrosion resistance while the carbon steel core delivers the structural integrity needed for concrete anchoring applications.

Why This Product

• Faster installation without sacrificing holding strength - the built-in expansion mechanism means crews can drive the anchor and move on immediately, cutting labor time on repetitive concrete fastening tasks.
• Tamper-proof design for added security - the mushroom head makes unauthorized removal difficult, providing peace of mind for applications like suspended ceiling panels, sprinkler pipe hangers, and formwork attachments.
• Versatile across multiple concrete anchoring applications - a single anchor size handles a wide range of tasks, from light structural fastening to overhead support, reducing the need to stock multiple anchor types.
• Trusted Simpson brand engineering - Simpson Strong-Tie is a recognized name in structural connectors and anchoring systems, and the Crimp Drive line reflects the same design discipline applied to everyday concrete fastening.
