Reisser Cutter Pozi Screws are high performance all purpose self countersinking screws. They allow for fast and accurate driving into softwood, chipboard, and most hardwood. Designed with two patented slots to prevent splitting when working close to the edge. Ribs and tucks under the head ensure flush fitting without surface damage. The screws feature a waxed thread and are zinc and yellow passivated, offering up to 20 times more rust resistance compared to standard BZP screws. A 20 degree needle point penetrates most timbers without requiring a pilot hole. The wide, deep thread is engineered to reduce driving resistance by up to 40 percent. A reinforced collar prevents snapping, providing durability. These screws are designed for maximum precision and durability.
