What is a Threaded Rod?
A threaded rod is a long, straight bar made of metal, commonly steel, that has threads running its entire length. This unique design allows the rod to be used with nuts and washers from both ends, making it ideal for applications that require continuous fastening or anchoring through various materials. Unlike traditional bolts, threaded rods offer versatility in length and application.
Types of Threaded Rods
Coarse Threaded Rods
Coarse threaded rods are widely used in construction for their ability to create strong connections quickly. They typically feature a thread pitch of 20 threads per inch, making them suitable for general fastening tasks. Retailers like Lowe’s and Tractor Supply provide a variety of lengths for these rods.
Stainless Steel Threaded Rods
Stainless steel rods are available in two primary grades: 304 and 316. The 304 grade is suitable for most indoor applications, while the 316 grade provides superior corrosion resistance, making it ideal for marine environments. Fasteners Plus offers a comprehensive range of stainless steel options.
Brass Fully Threaded Rods
Brass threaded rods are less common but are used for specific applications, such as electrical connections and decorative projects. Their aesthetic appeal makes them suitable for visible installations. Grainger and Bolt Depot offer these in various lengths.
Galvanized Threaded Rods
Galvanized rods are coated with a layer of zinc to enhance corrosion resistance. They are commonly used in electrical support and outdoor applications. Home Depot is a reliable source for galvanized threaded rods.
