Description
Wooden Screw is a metal screw with a sharp point designed to attach two pieces of wood together. Wood screws are commonly available with flat, pan or oval-heads. A wood screw generally has a partially unthreaded shank below the head. The unthreaded portion of the shank is designed to slide through the top board (closest to the screw head) so that it can be pulled tight to the board it is being attached to. Twin-fast wooden screw is available too. A Twin-fast screw is a type of screw with two threads so that it can be driven twice as fast as a normal (i.e. single-start) screw with the same pitch. Dry wall screws designated as fine are the most common screws to use the twin-fast style of threads.
