Self-countersinking screw
Quickscrews says its “silky smooth” Quickcutter is the most advanced woodworking screw on the market. The Type 17 Point allows for a fast start and eliminates the need for a pilot hole, while the extra groove in the shank alleviates pressure and eliminates splitting. The nibs under the head self-countersink the screw, saving time and labor, the company adds.
