The Borefast Anchor & Screw in One is the best one-piece anchor for fastening into drywall and masonry materials. Borefast anchors self-drill through drywall and easily penetrate both wood and metal studs. They also fasten into concrete, brick, block and plaster when a 3/16" hole is pre-drilled. Borefast anchors meet or exceed drywall load values versus most competing drywall anchors.
