MASONRY ANCHOR SCREW HEX GAL M20 X 170MM

These screwbolts are a hex head high tensile self-tapping concrete and masonry screw anchor for use in a whole range of base materials such as concrete, block, brick, timber, marble, and stone. The screwbolt is suitable for close to edge applications as the cutting thread does not expand or put pressure on the surrounding substrate. Installation is quick and easy, drill, clean the hole and screw in the screwbolt. Other advantages of the screwbolts are easy removal and surprisingly high loads.
