The finger joint is the most common joint used to form long pieces of lumber from solid boards the result is finger-jointed lumber. The strength of a finger joint comes from the long-grain to long-grain contact between the fingers. It provides a solid gluing surface. The number of contact points also allows for more gluing surface as opposed to a butt joint or a rabbet joint. The minimum thickness is 7/16″ (11mm), requiring the one-finger assembly. The maximum thickness of 1 3/8″ (36mm), is implemented with the five-finger assembly.
