Instead of the typical combination of head and thread, a dowel screw has lag threads on both ends and an un-threaded center you can tighten with a pair of locking pliers or a driver tool. Both ends have standard right-hand threading, so the installer turns the dowel screw clockwise. As a thread-forming-type screw, a dowel screw creates its own mating thread as it goes into wood. Some professionals also call dowel screws wood screw threaded studs.
As woodworking fasteners, dowel screws connect pieces of wood. They suit applications where you need to join two pieces of wood with a hidden fastener and blind holes. Projects that involve dowel screws include:
When installing a dowel screw, you need to drill a pilot hole at both points you plan to attach. Remember to use a drill or driver bit and type that matches the inner diameter of the screw. We welcome you to contact our team if you need help choosing the right combination of dowel screw and bit. The type of wood you work with also impacts the size of the pilot hole you should drill. Hard wood often needs a slightly larger hole size than soft wood.
