The Borefast anchor and screw in one is the excellent 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 in hole is pre-drilled. Borefast anchors meet or exceed drywall load values versus most competing drywall anchors.
