Product Description
Simpson CSD25400 CSD 1/4 in. x 4 in. Zinc-Plated Split-Drive Anchor is a one-piece mechanical expansion anchor from Simpson Strong-Tie, engineered for fast, reliable fastening into concrete, grout-filled block, and stone. As the anchor is driven into the pre-drilled hole, the split-type expansion mechanism on the working end compresses and exerts outward force against the walls of the hole, creating a secure hold without the need for adhesives or setting tools. The countersunk head sits flush with the surface, making it ideal for attaching wood or light gauge steel cleanly to concrete and grout-filled block surfaces.
