Ultra high performance woodscrews with TTX® drive, Cyclone ribs, self countersinking, lubrication, low torque thread pitch, high strength and maximum pull-out resistance.
The R3® Bias Thread Tip gives instant grab and a fast start, acting as a hole former that pushes wood fibres aside to help prevent splitting without a pilot hole. The flat Cyclone rib head profile allows the screw to sit flush in hinges and hardware and the design is compatible with plastic expansion plugs.
