Introduction of Roofing screw
Roofing screw is a commonly used screw that uses a special tail and can be screwed in and out using a regular screwdriver. Because the tail is sharp, it can directly cut open the surface of the wooden board to achieve the purpose of screwing in.There is a plastic ring inside the screw cap, which should be used for sealing. This waterproof screw cap also has this type of plastic ring.
