They also come with a pin that is fixed that is perfect for doors that cannot be opened with the removal of the pin. Other types of butts hinges include a plain bearing with grease that reduces friction and allows the hinge to move with minimal force. They are ideal for use on lighter items, such as cabinet doors.
