1/2-in x 3-in Sleeve Anchors U94871

The Red Head Acorn Head Sleeve Anchor is a masonry anchor that is used primarily for fastening into porous concrete, brick and block. It features a button style head that uses a nut driver drill bit to drive the anchor into the concrete and then requires tightening the button head with a wrench, allowing for the anchor to properly expand inside the concrete. This Red Head contractor grade acorn head sleeve anchor comes with a pre-assembled washer and nut, making installation easy and efficient.
