Hillman 1/2 In. x 3 In. Hex Head Sleeve Anchor (12 Ct.)

Concrete Sleeve Anchors design allows them to anchor into concrete, brick and block.

Turning the nut pulls the working end of the sleeve anchor up through the sleeve, expanding and anchoring itself securely in the base material.

Sleeve anchors have many uses including, but not limited to frame installations, electrical and mechanical attachments, and masonry applications.
