High performance all purpose self-countersinking screw for fast accurate driving into softwood, chipboard and most hardwood. Features 2 patented slots to prevent splitting close to the edge, and ribs and tucks to enable flush fitting without surface damage. Waxed thread and Zinc and yellow passivated coating provide up to 20x more rust resistance than standard BZP screws. The 20deg needle point is sharp enough to penetrate almost all timbers without the need for a pilot hole. A wide, deep thread is designed to reduce driving resistance by up to 40%, meaning less torque is required for faster completion of the job. The reinforced collar prevents snapping and provides depth. Presented in eye-catching, informative packaging, the Cutter leads the way in premium High Performance Woodscrews.
