Threaded Rod in Zinc Plated Steel

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 or sammy screws. This makes threaded rod excel at tension applications specifically.

Threaded rod in this selection comes in Grade A307 steel with a zinc plating applied. Grade 307A, or A307, steel is an ASTM grade of carbon steel intended for general purpose applications. It's SAE equivalent would be a Grade 2 steel.

Zinc is by far the most common and ecnomical type of plating for fasteners. The zinc plating adds a protective "sacrifical" top layer against corrosion while also adding a shiny finish to the threaded rod. Zinc plated threaded rod is ideal for indoor use where it won't be constantly exposed to harsh elements.

FAQs

What is threaded rod used for?

Threaded rods have various applications, effectively being used as a pin to fasten or connect two materials together. 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.

What is grade a307?

Grade 307A, or A307, steel is an ASTM grade of carbon steel intended for general purpose applications. It's SAE equivalent would be a Grade 2 steel.

What is zinc plated steel?

Zinc plated steel is steel that goes through the process of adding a layer or coating of zinc to protect the steel from corrosion. The added layer of zinc sacrifices itself to keep the steel from rusting, even if the plating is damaged.

Is zinc plated steel rust proof?

No. Zinc plating adds a layer of corrosion resistance for rust protection. Still, it's a thin plating, and it's not as rust resistant as hot-dip galvanizing, which also uses a zinc top layer. While not the most corrosive resistant of materials, zinc plating is easily the most economical and commonly used.

Can zinc plated steel be used outside?

Zinc plating is not a good form of corrosive protection for outdoor use, especially near saltwater or in marine environments. For those applications, stainless steel or potentially hot-dip galvanized steel would work better. Zinc-plated steel is better for indoor use.
