A butt hinge is comprised of two leafs with three or four knuckles and pins, which join to form a curved barrel also known as the knuckle. The knuckle, or barrel, is the hinge's main pivot point, and is normally secured to the leafs using screws or other fasteners. One of the primary advantages of butt hinges is their capacity to handle heavier loads over other hinges. This is due to their larger knuckle is more supportive of leafs. Butt hinges are more resistant to extreme temperatures since they have a larger capacity to expand and contract. Butt hinges are also installed on recessible surfaces.

To avoid this, it is recommended to regularly clean and lubricate the hinges. This will stop friction from destroying the knuckles, and will keep them running efficiently. Some butt hinges use a ball bearing between the knuckles in order to reduce friction. These hinges are perfect for heavy-duty, high-use doors. They also come with a pin that is fixed, which makes them ideal for doors that can't be opened with the help of removing it. Other types of butts hinges include a plain bearing lubricated with grease that reduces friction and allows the hinge to be moved without much force. These hinges are best suited for light-weight applications, such as cabinet doors. These pins are also available with spun-ends, which ensure the pin is permanently secured in place. Butt hinges are commonly used in residential settings, however they are also popular in commercial and industrial applications.
