Reisser Cutter Pozi Screw is a high performance all purpose self countersinking screw for fast accurate driving into softwood chipboard and most hardwood. It features patented slots to prevent splitting when screwing close to the edge. Ribs and tucks under the head ensure flush fitting without surface damage. The waxed thread reduces friction. Zinc and yellow passivated coating provides up to 20x more rust resistance than standard BZP screws. A sharp 20 degree needle point penetrates most timbers without a pilot hole enabling quick work. The wide deep thread reduces driving resistance by up to 40 percent requiring less torque and speeding up the job. This screw offers a reinforced collar for strength and a durable finish.
