ABSTRACT:
At least one scored screw is driven into the squeak area with a specialized driving bit and an alignment and depth control fixture. The alignment and depth control fixture is used to direct the scored screw to the proper point into the floor so that the scored area is at or beneath the surface of the floor. The driving bit can stop driving the screw at the desired position. After the alignment and depth control fixture is removed, a gripping tool is used to apply force to the screw and break the screw at the prescored position. The barrel of the screw being left in the floor locks the floor or the step to the desired support. One screw or series of these screws in usually an arcuate or a radial fashion around the squeak area, can eliminate the squeak.
