The Kreg 1-1/4-Inch Pocket Hole Screws are ideal for hardwood applications. This 1-1/4-inch fine thread works well in 3/4-inch thick, hardwood material such as oak, maple, hickory, cherry and walnut. The wide bearing of the washer head will not overdrive in the bottom of the pocket. The screw also features a type 17 auger tip that self-taps its own hole, eliminating the need to pre-drill in even the hardest materials. The large diameter steel shanks feature a bronze finish and a dry lubricant coating that eases driving torque and provides greater rust resistance. Cut-thread pattern prevents splitting. Coarse thread is for any combination of softwoods, plywood, and composites, and fine is for hardwoods. These screws come in a pack of 100.
