Floorboard screws are a specific type of thread-cutting screw designed to drive straight through the boards and into the substrate. Thread cutting screws are designed to create new threads in existing holes. They are commonly used in applications in need of periodic maintenance involving wood, metal, or plastic. Thread cutting screws do not generate as much stress on material as thread-forming screws. Thread cutting screws feature a blunt, tapered point and cutting edges to assist with thread creation and material removal.
