Concrete screws are ideal for light duty application in concrete when risk of cracking is high. Often the size and width that is closer to that of a standard screw, these fasteners can be firmly embedded into many types of masonry when fixing window frames, patio doors and the like. And for functionality and a more visually-integrated appearance (without bulky bolt heads), these screws come in flat-top phillips drive head, as well as the standard hex head configuration.
Also, no plastic or nylon plugs are required in concrete, stone or brick, and they are designed to cut their own thread in the material. If the screw is removed, it can be re-embedded by hand; the self-cut thread simply matches with the screw’s thread again.
