At what angle is a "half-lap joint" commonly used?

A half-lap joint is commonly utilized at a 90-degree angle to join two pieces of wood together. This type of joint involves removing half of the thickness of each piece at the point where they overlap, creating a flush surface when they are joined. The resulting joint is both strong and stable, making it particularly suitable for frames, beams, and various structural applications in carpentry.

Using a half-lap joint at a 90-degree angle allows for a secure connection that can withstand significant forces, which is crucial in construction and furniture making. This joint is frequently employed in applications such as frame assemblies, where strength and alignment are essential, highlighting its role in maintaining both structural integrity and aesthetic appeal.

Other angles like 45, 30, or 60 degrees do not typically characterize the traditional use of a half-lap joint and may serve different joint types or purposes, such as miter joints or other specialized connections.
