A butt hinge is made up of two leaves that have three or more knuckles, a pin and a barrel with a curving. The knuckle, also known as the barrel, houses the hinge's pivot point, and is normally attached to the leafs by screws.
Butt hinges can support heavier loads than other hinges. This is due to their bigger knuckle is more supportive of leafs. Additionally the hinges on butts have a greater capacity for expansion and contraction, making them more able to withstand extreme temperatures.

Other types of butts hinges include a plain bearing lubricated with grease, which reduces friction and allows the hinge to be moved with the least amount of force.
