Butt hinges are the most common type of hinges used on entry doors and passage doors, as well as some cabinet doors. The hinge consists of two leaf plates, one anchored to the edge of the door and the other to the door jam. The leaf plates come together and are hidden between the door and frame when the door is closed so that the only thing visible is the barrel of the hinge, containing a pin that holds the hinge's leaf plates together. This type of hinge is also known as a mortise hinge, due to the fact that the two leaf plates are recessed into mortises cut into the edge of the door and door jamb. For indoor use, butt hinges are usually made of steel; exterior doors and outdoor applications call for stainless steel.
