A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. It is a flexible joint that supports a door and allows it to swing. Hinges are used to join two parts together while allowing them to rotate relative to each other. They typically have two flat faces, known as leaves, and may come in various types such as butt hinges, ball bearing hinges, concealed hinges, gate hinges, and overlay hinges. Hinges are essential for various applications, including doors, cabinets, gates, and furniture. The most common types of hinges include:
- Butt Hinge: The most common type used on doors, with three different variations: plain, ball bearing, and spring-loaded.
- Ball Bearing Hinge: It has lubricated bearings between the hinge's knuckles to reduce friction, making it ideal for heavy entryway doors or those that sustain frequent use.
- Concealed Hinge: Designed to be hidden when doors are closed, they can be self-closing and are adjustable, commonly used for cabinets.
- Gate Hinge: Able to withstand considerable forces exerted by a gate, often including an adjustment and suitable for outdoor use.
- Overlay Hinge: Designed for doors that lie on top of the cabinet opening rather than fit into it.
Hinges come in a variety of materials, including stainless steel, brass, bronze, pewter, and copper, and may require tools such as a chisel, utility knife, hammer, screwdriver, and drill for installation
