Threaded rod is a type of fastener with threads typically  cut or rolled throughout the length of the rod. These rods resemble a stud, yet  tend to be much longer than a standard stud. Threaded rods do not have  heads or washers like those found on a screw or bolt. Threaded rod is sometimes  known as all-thread. 
                 
                These fasteners can be used to join wood or metal together,  acting as a pin to connect the two materials. They are often inserted into  concrete or wood during a repair, and can be used to stabilize structures  ranging from wooden furniture to concrete walls. Builders and contractors may  also use a threaded rod when constructing homes or other types  of buildings. These threaded rods are also popular with metalworkers when  building furniture or consumer goods. 
                 
                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. 
                 
                Titanium threaded rod is surprising cost effective,  especially when you consider zero cost of replacement due to corrosion.
