1. Using the counter snap fixture, screw the counter snap screw into your hardwood floor.

2. When the screw head hits the top of the fixture, the pressure will build and the screw will snap at 1/8 IN. below the surface of your floor.

3. The result has the mechanical holding strength of a screw, leaving a hole the size of a countersunk finishing nail. Simply fill the hole with a wood filler or putty, and you'll have 2 inches of hidden screw securing the subfloor to the joists and permanently getting rid of your squeak problem.
