The Simpson 1/4 x 1 1/2 Countersunk Head Crimp Drive Anchor is an expansion anchor from Simpson engineered for reliable fastening in concrete and grout-filled block. The preformed curvature along the shaft acts as a built-in expansion mechanism, securing the anchor in place upon installation without any secondary tightening step. The countersunk head style delivers a flush, zero-profile finish, making this drive anchor well suited for applications ranging from attaching concrete formwork to hanging overhead support for sprinkler pipes and suspended ceiling panels.

Key Features

• Unique curved shaft design - creates a secure expansion fit in the base material, reducing the risk of loosening over time without relying on separate hardware or extra steps.
• No secondary tightening required - the built-in expansion mechanism locks the anchor in place upon driving, cutting installation time and simplifying the fastening process on the job site.
• Countersunk head provides a zero-profile solution - the head sits flush with or below the fastened surface, keeping finished surfaces clean and unobstructed where a protruding head would interfere.
• Zinc-plated carbon steel construction - provides a corrosion-resistant barrier suited for interior concrete and grout-filled block applications.

Why This Product

• Faster installation workflow - eliminating the secondary tightening step means crews can drive and move on, making this crimp drive anchor a practical choice for high-volume fastening tasks in concrete and block.
• Versatile application range - the same anchor handles fastening wood or light-gauge steel, attaching concrete formwork, and supporting overhead loads such as sprinkler pipes and suspended ceiling panels, reducing the need to stock multiple anchor types.
• Flush finish where it matters - the countersunk head is ideal for situations where surface clearance is critical, such as panel installations or formwork applications that cannot accommodate a raised anchor profile.
• Trusted expansion anchor design - the preformed shaft curvature is a purpose-built mechanical feature, not a friction-only solution, giving buyers confidence in consistent, repeatable placement across concrete and grout-filled block substrates.

Frequently Asked Questions

What base materials is the Simpson CD25112C Crimp Drive anchor designed for?

The Simpson Strong-Tie Crimp Drive anchor is designed for use in concrete and grout-filled block, making it well suited for a variety of structural and support fastening tasks in these substrates.

Why does the Crimp Drive anchor not require a secondary tightening procedure?

The anchor features a preformed curvature along the shaft that acts as a built-in expansion mechanism. When driven into the hole, this curved shaft design expands and secures the anchor in place automatically, eliminating the need for any additional tightening step.

What does the countersunk head style offer compared to other head types?

The countersunk head provides a zero-profile solution, meaning the head sits flush with or below the surface of the material being fastened. This is ideal for applications where a protruding anchor head would be undesirable.

What material and finish is the CD25112C anchor made from?

The CD25112C is constructed from carbon steel with a zinc-plated finish, which provides a level of corrosion resistance suitable for the anchor's intended indoor and protected fastening applications.
