Wood screws are made in various sizes and thickness. Size of a wood screw is normally expressed by inches or milli-meters and thickness by numbers. ½ x 4 means a wood screw of half inch length having 4 gauge thickness. Regarding the length of the threads, in general terms, it is known as half threaded or full threaded (Twinfast) wood screw. In Twinfast type of wood screws, two threads are moving parallel with each other to penetrate into wood at a faster rate with the help of a screw driver.
