    A threaded rod is a type of metal fastener with threads cut into both ends. These rods resemble the shank of a screw, yet tend to be longer and thicker than a standard screw. Threaded rods do not have heads or washers like those found on a screw on bolt, and tend to be the same diameter along their entire length. Depending on the model, a threaded rod may feature threads along the entire length, or simply at either end. This product is sometimes known as all-thread, and can also be referred to simply as a stud.

    A thread rod also serves as a popular method of hanging sheet metal ducts and other equipment within a building. Installers attach one end of the rod to the ceiling structure, then thread the other end into a special fastener or clip. These clips or fasteners can then be used to hang ductwork, light fixtures, or mechanical equipment.

    A threaded coupler is a device designed for joining various types of threaded parts to one another. While there are several different types of couplers an individual can choose from, most couplers are designed for specific applications. For example, some couplers are designed to join threaded rods together, while others are only intended for joining lengths of pipe. The primary difference between couplers for rods and those meant for pipes is what is known as the thread pitch. Pipe threads are slightly different than those found on nuts and bolts, so a threaded pipe coupler cannot replace a rod coupler, and vice versa.

    The primary purpose of a threaded coupler is to connect two sections of pipe, rod, or tube together using threads. Normally, couplers have what are known as internal threads. It may be easier to understand this idea when thinking about the cap on some types of milk jug or other plastic beverage bottles as examples of basic threaded couplers. The threads inside the cap are internal, and the threads on the jug are external. Similarly, a short length of pipe with internal threads at both ends may serve as a coupler.
