What is a dowel used for in construction?

A dowel is primarily used to fashion two members together, serving as a connecting element that provides alignment and stability in various construction applications. Dowels are cylindrical rods, typically made of wood, plastic, or metal, that are inserted into aligned holes in two separate pieces, allowing them to be fastened securely. This method of connection is commonly used in furniture making, cabinetry, and other woodworking projects to achieve a strong joint without visible fasteners.

In construction, dowels can play a role in creating stronger and more durable joints by distributing loads evenly across the connected members. Their ability to offer a flush finish is also helpful in aesthetic applications where visible hardware might detract from the design.

The other choices do not accurately reflect the primary purpose of a dowel in construction. While they serve important functions in building, they do not align with the specific definition and application of dowels.
