Simpson Strong-Tie CD37300M Crimp Drive® 3/8 in. x 3 in. Zinc-Plated Mushroom Head Anchor (25-Qty)

The Simpson Strong-Tie® Crimp Drive anchor is an easy-to-install expansion anchor for use in concrete and grout-filled block. The preformed curvature along the shaft creates an expansion mechanism that secures the anchor in place and eliminates the need for a secondary tightening procedure. The anchor is available in five different head styles to handle different applications that include fastening wood or light-gauge steel, attaching concrete formwork, and hanging overhead support for sprinkler pipes or suspended ceiling panels.
