Simpson 3/16 x 4 Mushroom Head Crimp Drive Anchor CD18400M

The Simpson Strong-Tie Crimp Drive anchor is an easy-to-install expansion anchor for use in concrete and grout-filled block. The pre-formed curvature along the shaft creates an expansion mechanism that secures the anchor in place and eliminates the need for a secondary tightening procedure. This speeds up anchor installation and reduces the overall cost. The low profile mushroom head works excellent for attaching wood or light-gauge steel to concrete and grout-filled block.
