Other types of butt hinges are a plain bearing with grease that reduces friction allowing the hinge to move at a minimal force. These hinges are ideal for applications that require less force such as cabinet doors. These pins can also be purchased with spun-ends to ensure that the pin is permanently secured in place.

Butt hinges are typically used in residential settings, but they are also popular for industrial and commercial applications. For instance, they are employed in research and medical facilities to shield patients from radiation and neutron contamination as well as vault doors and security systems.
