Anchor, Hillman, Split-Drive, Flat-Head, 1/4 in x 20 3 in

Split drive anchors have been designed for permanently fastening items on to solid concrete materials. To use, begin by pre-drilling a hole into the concrete. Then, insert the working end of the split drive anchor through the fixture and into the pre-drilled hole. As the anchor is driven into the hole, the pre-expanded halves at the base of the anchor continually push against the concrete, striving to regain their original shape. This action gives these anchors stability and permanence.

• One-piece, pre-expanded anchors designed for permanent, tamperproof installation
• Easily installed with a hammer after a hole has been pre-drilled
• For concrete applications only
• Flat head style is particularly suited for wood-to-concrete anchoring
