Butt Hinge Applications
Butt hinges are a type of hinge with rectangular parts that fasten to two separate, parallel parts that close on each other, thus connecting them and allowing for swinging movement up to 180 degrees. One of the two most common types of recessed, or mortised, hinges, butt hinges do not necessary have to be mortised and can be surface-mounted as well.
Compared to any other hinge, the butt hinge is by far thesimplest in design, most affordable, and used most often for hingeapplications. Butt hinges are always in constant use as they are typically usedto hang and swing doors, cabinets, gates, trunks, chests, and other commonitems that open and close. The hinge is made up of two leaves that are attachedto two adjoining parallel parts. The leaves are bent together at their edges tocreate knuckles in which a pin is inserted into to secure the two leavestogether allowing for movement to take place. This pin can either be loose orfixed depending on the application. A loose pin allows the two pieces to beseparated without removing the hinge from the object. These are commonly usedon interior doors of a home for easy removal and reattachment. Fixed pins aresecure and will not come out as their name suggests. Gates and garage doors arecommon places for this type of hinge to be found as they are more permanentfixtures that are not often tampered with.
Butt hinges are made out of various materials includingbrass, copper, stainless steel, bronze, titanium and more. They can be usedindoors and outdoors, however when using them outdoors a corrosion and rustresistant material should be chosen to lengthen the life of the hinge. Hingescan also be decorative and match any other hardware that is mounted on aparticular piece. A variety of lengths and thickness are available to get theright combination of strength and durability for any application. Manufacturerstypically create these hinges with pre-drilled screw patterns to accommodatefasteners easily for quick placement. These hinges can create up to 180 degreesof movement between the parts they connect.
As the premier type of hinge used in furniture applications, butt hinges are used to mount interior and exterior doors, cabinets and more in residential, construction, commercial, public, architectural, military, marine and other industrial contexts. When used for commercial and residential furniture applications, butt hinges are typically constructed from steel, though butt hinges for exterior doors may also be made of brass or stainless steel for high corrosion resistance. For residential cabinetry, butt hinges can be made of more aesthetically-pleasing materials such as satin nickel, antique brass, polished nickel and satin brass. For industrial applications, heavy duty butt hinges are required and are most often constructed from materials such as steel, stainless steel and brass. Aluminum butt hinges are mainly used for light-weight applications.
Butt hinges consist of two metal leaves that are bent at their edges into barrels. The barrels are known as knuckles, and a pin is inserted into the barrels and runs along the entire length of the hinge. One leaf of the hinge is connected to an object such as the door while the other leaf is connected to, and recessed into as well, the parallel part that needs to be connected such as a jamb or door frame. There are two main types of pins that are used in butt hinges: fixed-pin and loose-pin. Fixed-pin butt hinges are rigid and the pin cannot be removed from the butt hinge. Loose-joint butt hinges allow the pin to be easily removed from the butt hinge by tapping it with a screwdriver. Loose-joint butt hinges have an advantage over fixed-pin butt hinges in that doors can be removed without having to unscrew the hinges. Besides the common butt hinge, there is one other type of butt hinge that is commonly used, known as a rising-butt hinge. Rising-butt hinges are self-closing and are used on doors in areas where there is a discrepancy between the height of the flooring, such as a cement floor and a carpeted floor. When the door is opened, the rising-butt hinge causes the door to rise high enough that it clears the higher flooring. Materials for butt hinges are typically extruded for additional tensile strength and then drilled and cut to shape. More Butt Hinges Information
