Dowel screws are specialized fasteners used primarily in woodworking applications. These screws feature a dual-threaded design, with one end typically having wood threads and the other end machine threads. They are commonly used to join two pieces of wood together by screwing into one piece while the other is drilled to accept the screw. Dowel screws provide a strong and secure connection, making them popular for furniture assembly, cabinetry, and other woodworking projects.
