All Purpose Masonry Screw
Masonry screws†are used to fix into concrete, brick, wood, marble and stone. Simply drill a 6mm hole into the masonry and tighten the screw with a T30 (torx) bit using an impact driver, drill or electric screwdriver. The screw will tap its own thread into the hole, no plug or resin needed! Sold individually, discount available for box quantities.
