Prevents door sagging and protects the frame.
A door hinge is a mechanical hardware device that connects a door to its frame, allowing the door to open and close smoothly. Most door hinges consist of two metal plates and a knuckle joint that rotates on a pin.
The three most commonly used door hinge types are:
Butt Hinges – Standard hinges used for residential and commercial doors.
Ball Bearing Hinges – Heavy-duty hinges designed for smooth, long-term performance.
Concealed Hinges – Hidden hinges often used for cabinets or modern interior doors.
For regular wooden or metal doors, butt hinges or ball bearing hinges are typically used. Heavy front doors usually use 4BB (four ball bearing) hinges for durability.
A door hinge may also be called a butt hinge, door joint, or pivot hinge, depending on its structure.
The word “hinge” comes from the Old English word heng meaning “to hang.” A hinge literally allows a door to “hang” and swing from the frame.
A standard door hinge includes:
Leaf / Plates
Knuckle / Barrel
Pin
Bearing rings (for ball bearing hinges)
Screw holes
The most common hinge used in doors is the butt hinge, widely used for interior and exterior wooden doors.
Most door hinges are removable, especially loose-pin hinges where you can remove the pin. However, fixed-pin hinges (often used for security doors) are not designed to be taken apart.
Yes. Replacing a door hinge is a simple DIY task. You only need a screwdriver, drill, and basic hardware knowledge.
To remove a door hinge:
Fully open the door
Support the door from below
Unscrew the hinge plates from the frame
Remove the pin if it’s a loose-pin hinge
You can remove the hinge pin using:
A screwdriver
A pair of pliers
A pin removal tool
Tap lightly upward with the handle of a tool if needed.
Front doors typically use heavy-duty stainless steel hinges or ball bearing hinges (BB hinges) because they support more weight and resist corrosion.
Examples include butt hinges, ball bearing hinges, concealed hinges, pivot hinges, and spring hinges.
Double action hinges or parliament hinges allow a door to fold back almost 180° or swing in both directions.
A hinge allows movement, while a latch secures the door in a closed position. They function differently but are both essential door hardware components.
Anything that allows two parts to rotate or pivot relative to each other is considered a hinge—for example, door hinges, cabinet hinges, or even mechanical joint hinges.
