The Simpson 1/4 in. Rod-Coupler Head Crimp Drive Anchor is an easy-to-install expansion anchor from Simpson engineered for use in concrete and grout-filled block. Its preformed curvature along the shaft creates a built-in expansion mechanism that secures the anchor firmly in place upon installation, eliminating the need for a secondary tightening procedure and keeping projects moving efficiently. The rod-coupler head accommodates threaded rod attachments, making this anchor a practical choice for overhead support applications such as hanging sprinkler pipes and suspending ceiling panels. Available in five head styles across its product family, the Crimp Drive line is designed to handle a wide range of fastening tasks, from attaching wood or light-gauge steel to concrete, to securing concrete formwork.

Key Features

• Unique curved shaft design - acts as a built-in expansion mechanism that locks the anchor securely in concrete or grout-filled block without any post-installation adjustment
• No secondary tightening required - the self-securing design reduces installation steps, helping contractors and installers complete anchor work faster and with less effort
• Rod-coupler head style - allows for threaded rod attachments, making the anchor well-suited for overhead support systems including sprinkler pipe hangers and suspended ceiling assemblies
• Zinc-plated carbon steel construction - the zinc-plated finish provides a protective coating over the carbon steel body, helping maintain anchor integrity in typical concrete fastening environments
• 1/4 in. anchor size with 3/16 in. drill bit diameter - precise sizing requirements are clearly defined, ensuring a correct and consistent installation every time

Why This Product

• Faster installation without sacrificing holding strength - the preformed shaft curvature eliminates the secondary tightening step required by many traditional expansion anchors, cutting labor time while still delivering secure placement in concrete and grout-filled block
• Purpose-built for threaded rod applications - the rod-coupler head is specifically designed to accept threaded rod, making this anchor a direct fit for overhead support work such as suspended ceilings and sprinkler pipe hangers rather than requiring adapters or workarounds
• Versatile across multiple concrete fastening tasks - a single anchor design handles fastening wood or light-gauge steel, attaching concrete formwork, and supporting overhead systems, reducing the number of different anchor SKUs a crew needs on the job
• Engineered by Simpson for concrete and grout-filled block - purpose-designed for these specific substrates, the Crimp Drive anchor is a reliable choice when the installation surface is concrete or grout-filled masonry block
