A butt hinge consists of two leaves with three or more pins, knuckles and a barrel that is curved. The knuckle, or barrel, houses the hinge's pivot point and is usually secured to the leafs using screws or other fasteners.

One of the primary advantages of butt hinges is their capacity to accommodate heavier loads as compared to other hinges. This is due to their larger knuckle offers more support to leafs. Butt hinges are more resistant to extreme temperatures as they have more capacity for expansion and contracting.

Butt hinges have their own set of drawbacks. For instance, the amount of friction they produce can wear down the hinge over time. It is recommended that hinges are regularly cleaned and lubricated to minimize this. This will prevent friction from wearing the knuckles down and will ensure that they are working efficiently.

Some hinges with butts utilize a ball bearing between the knuckles in order to reduce friction. These hinges are ideal for doors that require heavy-duty, high-use. They are also available with a pin that is fixed which is ideal for doors that are secure and cannot be opened with the removal of the pin.

Other types of butts hinges include a plain bearing lubricated with grease that reduces friction and allows the hinge to be moved with minimal force. These are recommended for use on lighter items, such as cabinet doors. These pins are also available with spun-ends, which ensure the pin is permanently secured in the correct position.

Butt hinges are used in commercial and residential settings.

Butt hinges are available in various sizes and weights to accommodate different door weights and sizes. The type of application and the desired level of durability and functionality will determine the type of hinge to choose.
