Threaded rods are metal fasteners with threads at both ends used to join wood or metal together, stabilize structures, and hang equipment. They come in various materials, lengths, diameters, and thread types. Buyers should consider the application when selecting the right product.
A threaded rod is a type of metal fastener with threads cut at both ends. These rods resemble the stem of a screw, but 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 design, a threaded rod may have threads along its entire length or simply at both ends. This product is sometimes known as an all-thread and can also be referred to simply as a stud.
These fasteners can be used to join wood or metal together, acting as a pin to connect the two materials. They are often set 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 threaded rod when constructing houses or other types of buildings. These threaded studs are also popular with metal workers when building furniture or consumer goods.
A threaded rod also serves as a popular method for hanging sheet metal ducting and other equipment within a building. Installers attach one end of the rod to the ceiling structure, then thread the other end through a special fastener or clip. These clips or fasteners can then be used to hang ductwork, light fixtures or mechanical equipment.
When choosing threaded rod, buyers must consider a number of factors to select the right product for the job. One of the most important decisions is the type of material each rod is made of. Standard steel or aluminum bars are the most popular options, with stainless steel varieties typically reserved for outdoor applications or corrosive environments. High-strength rods may be required to support heavy loads, and brass or zinc studs can be used to enhance visual appeal on certain types of projects.
Buyers should also consider the length and diameter of each threaded rod. These rods can usually be cut to size using a grinder or saw, but it’s often easier to choose the correct length from the start. Users also need to consider the type of thread on each rod. Lane threading may be needed for heavy-duty projects, while finer threads may be needed in more delicate materials or small projects. The ends of each rod can be chamfered or tapered to meet the needs of different applications.
