Need to hang something on concrete, brick, or block? These Hillman Hammer Drive Anchors are your go-to. This box comes with 50 anchors, each measuring 1/4” in diameter and 1-3/4” long. They're made of steel with a round head, designed for medium-duty fastening. Installation is simple: drill a 1/4” hole to the proper depth, insert the anchor, and then hammer the center pin until it's flush. This expands the anchor sleeve behind the material for a secure hold. Great for attaching brackets, electrical boxes, shelving, or light fixtures to masonry surfaces. Just make sure your drill bit is the right size and you're drilling into a solid material. A cost-effective, reliable fastener to keep in your toolbox for various projects around the house, garage, or workshop.
