A butt hinge consists of two leaves, three or more knuckles, a pin and a curved barrel. The knuckle or barrel, houses the hinge's pivot point and is typically attached to the leafs by screws or other fasteners.

One of the main advantages of butt hinges is their capacity to accommodate heavier loads over other hinges. This is because their larger knuckle is more supportive of leafs. Additionally hinges with butts have a greater capacity for expansion and contraction, which makes them more resilient to extreme temperatures.

To prevent this from happening, it is recommended to regularly clean and lubricate the hinges. This will stop friction from causing wear on the knuckles and will ensure that they are working efficiently.

Some butt hinges use a ball bearing between the knuckles in order to reduce friction. These are ideal for doors that see frequent use. They also come with pins that are fixed, making them ideal for doors that cannot be opened by removing it.

Other kinds of butts hinges include a plain bearing with grease, which reduces friction and allows the hinge to be moved with minimal force. These are suggested for lighter uses, including cabinet aluminium hinged doors. They are also available with spun ends to ensure that the pin is permanently fixed in the correct position.
