The Simpson 3/8 in. x 2 in. Mushroom Head Crimp Drive Anchor is an easy-to-install expansion anchor from Simpson designed for reliable fastening in concrete and grout-filled block. Its preformed curvature along the shaft creates a built-in expansion mechanism that locks the anchor securely in place without requiring any secondary tightening procedure, making it a practical choice for contractors and installers who need consistent, efficient results. The mushroom head configuration adds a tamper-proof quality suited for applications such as fastening wood or light-gauge steel, attaching concrete formwork, and hanging overhead support for sprinkler pipes or suspended ceiling panels.

Key Features

• Unique curved shaft design - the preformed curvature creates a self-expanding mechanism that holds firmly in concrete and grout-filled block, delivering secure and consistent placement every time.
• No secondary tightening required - the built-in expansion action eliminates an extra installation step, reducing labor time and simplifying the fastening process on the job site.
• Mushroom head style - provides a tamper-proof solution that resists unauthorized removal, making it well-suited for security-sensitive or overhead fastening applications.
• Zinc-plated carbon steel construction - the zinc-plated finish over a carbon steel body offers corrosion resistance for interior concrete and grout-filled block installations.
• Five available head styles - the Crimp Drive anchor line accommodates a range of applications including wood-to-concrete fastening, light-gauge steel attachment, formwork anchoring, and suspended ceiling support.
