A butt hinge is comprised of two leafs, each with three or four knuckles and a pin, which connect to create a barrel that is curved, also known as the knuckle. The knuckle, also known as the barrel, is the hinge's pivot point, and is normally secured to the leafs using screws.
One of the main advantages of butt hinges is their ability to take on heavier loads over other hinges. This is due to their bigger knuckle provides more support for leafs. In addition the hinges on butts are able to handle more expansion and contraction, which makes them more resilient to extreme temperatures.
Butt hinges can also be installed on recessed surfaces. This means that they won't be visible when the door is open or closed. This creates a smooth appearance and a more refined design. However, they could require routing for a flush finish.
Butt hinges come with a disadvantages. The friction that they create can, for example, wear out the hinges over time. 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 ensure they function smoothly.

Other types of butt hinges include a plain bearing with grease that reduces friction permitting the hinge to move with less force. These are recommended for lighter uses, including cabinet doors. They also come with spinned ends to ensure the pin is permanently fixed in place.

Butt hinges are available in various sizes and loads to fit different door weights and sizes. The type of hinge you choose will be determined by the application and the desired level of performance and durability. The load-bearing capacity of a hinge depends on the force that is applied to the hinge, and the length of time that it is exposed to this pressure.
