Threaded Rods are long rods that are fully threaded from end to end. They are similar to the threaded portion of a bolt but are much larger and do not feature a head. Also known as threaded bars, all-thread, and threaded studs, threaded rods are used to join and stabilize structures or objects, often into ceilings or walls.
Since threaded rod has threading running their entire length, they can fully engage nuts or other female-threaded components, such as coupling nuts. This makes threaded rod excel at tension applications specifically.
Threaded rod in this selection comes in hot-dip galvanized steel. Hot-dip galvanizing is done by submerging the fastener in molten zinc to provide a corrosion protecting finish. Essentially, the added zinc that's applied through the galvanization process serves as a "sacrificial" layer of protection to keep the steel underneath from degrading or being damaged.
You'll find hot-dip galvanized fasteners frequently used in situations where corrosion resistance is needed without the cost of stainless steel. It is considered superior to stainless steel in terms of cost and life-cycle. For applications where the fastener will constantly be exposed to corrosive materials, however, you'll want to use stainless steel instead.
Note: hot-dip galvanized fasteners tend to be a little larger, with thicker threading, because of the added layer of zinc. To compensate, hot-dip galvanized nuts are tapped larger to be thread effectively on hot-dip galvanized bolts. You will have difficulty trying to fasten non-hot-dip galvanized nuts to hot-dip galvanized bolts, screws, or all thread.
What is threaded rod used for?
Threaded rods have various applications, effectively being used as a pin to fasten or connect two materials. They are also used as supports to stabilize structures in some applications.
How is threaded rod measured?
Threaded rod is measured Diameter-Threading x Length. For example, you may find a threaded rod measuring 1/4"-20 x 6ft. The 1/4" is the rod's diameter, the 20 means there are 20 threads per inch of rod, and the 6ft is how long the rod is.
Is hot-dipped galvanized the same as galvanized?
Galvanization is the process of applying a protective zinc coating to steel or iron. Hot-dip galvanizing is a kind of galvanization in which the metal is dipped into a molten zinc bath. There are other kinds of galvanization, such as thermal diffusion galvanizing. In this process, the zinc (in powder form) and the parts are tumbled in a sealed rotating drum to cause galvanization.
What is hot-dip galvanized steel?
Hot-dip galvanized steel is steel submerged in a molten zinc bath to give the steel a protective corrosion resistant coating.
Can I use a hot-dip galvanized threaded rod with nuts of a different metal?
No. The hot-dip coating applied to the rod adds an extra layer to the steel. It may be difficult to fasten a nut of a different metal to the rod because of the threading's slightly larger size. This is why hot-dip galvanized nuts are tapped a little larger to compensate.
