Counter-Snap screws for at the joist-hardwood & linoleum floors
The Counter-Snap Hardwood & Linoleum Screws are for stopping squeaks at the joist. The screw is designed, by having two different pitches, to pull the floor and the subfloor tight to the joist. This stops the movement and squeaks. The screw is scored so when driven through the fixture it snaps 1/4 inch below the top of the floor. For hardwood floors, the small hole then can be filled with a wood filler to conceal the screw. The hole looks the same as the hole of a trim nail that is counter-sunk. In linoleum flooring, the linoleum expands back over the small hole making it very hard to see. Although the screw is not perfect it is about as close as you will ever get.
The key is to drill a pilot hole before using the Counter Snap screw so the wood does not split. Once you drill a pilot hole, drive the screw through the fixture as far as it will allow. The screw will pull the flooring together tight then snap 1/4 inch below the flooring. Then, simply fill the hole with wood filler.

Counter-Snap Linoleum Floor Screws fasten the floor tightly to the joist by going through the linoleum. The screw is designed to snap off 1/4 inch below the floor allowing the linoleum to expand back over the small hole making it very hard to see. Although the screw is not perfect it is about as close as you will ever get.
The key is to use an electric stud sensor to find the joist so the screw can go into the joist. Once you find the joist, drive the screw through the fixture as far as you can go. The screw will pull the flooring together tight then snap 1/4 inch below the flooring. The linoleum will expand back over the hole making it very hard to detect.
