dowel

A dowel is a cylindrical rod, typically made of wood but sometimes plastic or metal, used primarily in woodworking and joinery. It's a deceptively simple component with a long history, dating back to ancient carpentry techniques. The core function of a dowel is to provide a strong, yet often hidden, connection between two pieces of material.

Unlike nails, which rely solely on friction, or screws, which use threads to grip the wood, dowels are typically glued into precisely drilled holes. This creates a robust joint that is less likely to split the wood or weaken over time. Dowels are commonly used in furniture construction—think of chair legs attached to the seat, shelves secured within a bookcase, or drawer fronts joined to their boxes.

However, "dowel" is not only about woodworking. The term can also refer to a cylindrical pin or rod used to align, support, or connect parts. You might encounter dowel pins in mechanical engineering: small, carefully made metal rods that keep parts in the correct position inside machinery. Dowels are also common in crafts, model making, and household projects, where a plain round rod can be cut and used in many simple ways. Whether it is holding furniture together, helping parts line up in a machine, or serving as a basic building piece in a craft project, a dowel is a practical cylinder with a wide range of uses.
