Butt Hinge

Definition

A butt hinge is a hinge consisting of two plates with a removable connecting pin.

Purpose

Butt hinges are commonly used to attach doors to their frames, allowing the door to swing open and closed. The removable pin allows for easy installation and removal of the door without detaching the hinge plates from the door or frame.

Examples of Use

1. Interior Doors: Butt hinges are widely used for hanging residential and commercial interior doors.
2. Cabinet Doors: Smaller butt hinges are used for cabinet and cupboard doors.
3. Exterior Doors: Heavy-duty butt hinges support the weight and movement of exterior doors.

Related Terms

• Continuous Hinge: Also known as a piano hinge, it runs the full length of the door or panel, providing more even support.
• Pivot Hinge: A hinge that allows a door to pivot from a single point at the top and bottom, often used in heavy or high-traffic doors.
• Mortise Hinge: A hinge installed in a recess (mortise) cut into the door and frame, allowing the hinge to be flush with the surface.

Notes

Proper alignment and installation of butt hinges are crucial to ensure smooth operation of the door. Lubrication of the hinge pin can prevent squeaking and wear over time.
