A butt hinge consists of two leaves with three or four knuckles, and pins, which join to form a curved barrel, known as the knuckle. The knuckle or barrel is the pivot point of the hinge. It is typically connected to the leaf using screws.

Butt hinges are able to hold heavier loads than other hinges. This is because of their larger knuckle, which offers more support for the leafs.
