This particular threaded fastener is characterized by its long tapered shank that ends in a pointed tip. The head could be either slotted or recessed. The threading on the screw is also sharp and bears a coarse pitch for easy insertion to a wooden surface.
Oftentimes, the wood screw would have a shank that is partially unthreaded (starting from the underside of the screw head).
These screws form their own mating as they are drilled into a wooden surface. This ensures an extremely tight fit and an almost negligible chance of the screw backing out.
Fasteners Plus offers wood screws such as: flat Phillips, oval Phillips, round Phillips, flat slotted, oval slotted, and round slotted.
