Direct fastening into solid concrete and brick without expansion anchors. Deep dive into high-low thread designs, pilot hole depth, and masonry drill selection.
How Direct Concrete Screws Work
Concrete screws utilize alternating high and low threads with diamond-hard induction-hardened cutting edges. As the screw is turned into a precisely drilled pilot hole, the high threads cut their own deep mating groove into the concrete matrix, delivering high pull-out resistance without radial expansion stresses.
