Anchors
Concrete Screw Anchors
A self-tapping screw with a hardened, sharp thread that cuts into concrete, brick, or block without a separate anchor. It is driven into a pre-drilled pilot hole and can be removed and reused.
Used to attach fixtures, brackets, and framing directly to concrete and masonry. Bought by electrical and mechanical contractors for light to medium-duty fixing.
