Simpson Strong-Tie CSD/DSD Split-Drive Anchors, Countersunk Head, Zinc Plated

The Split-Drive anchor is a one-piece expansion anchor that can be installed in concrete, grout-filled block and stone. As the anchor is driven in, the split-type expansion mechanism on the working end compresses and exerts force against the walls of the hole.

• Available in countersunk (CSD) and duplex-head (DSD) styles
• DSD anchor can be removed with a claw hammer for temporary applications
