Simpson 1/4 x 2 Countersunk Split-Drive Anchor CSD25200

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. The Countersunk head allows for a smooth surface when attaching wood or light gauge steel to concrete and grout-filled block surfaces.
