Threaded Rod in Plain Grade B7 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 B7 alloy steel with no plating or coating on it. B7 is a heat-treated chromium molybdenum alloy steel under ASTM A193. This steel grade is in high demand in high-temperature and high-pressure applications thanks to its tensile strength and excellent heat resistance. You'll often find B7 steel used in industries where high temperatures and pressures are reached, such as the oil and gas industry or construction.

Having a plain "finish" means this threaded rod is very vulnerable to corrosion. Plain threaded rod is best used in non-corrosive, indoor environments and is the most economical choice for such applications. After all, if the threaded rod isn't going to be exposed to corrosion, why spend extra on plating or coating it?

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 b7 steel?

B7 is a heat-treated chromium molybdenum alloy steel under ASTM A193. This steel grade is in high demand in high-temperature and high-pressure applications thanks to its tensile strength and excellent heat resistance.

What is plain steel?

The term "plain steel" usually refers to carbon steel or mild steel with no plating or coating.

What kind of steel is plain steel?

Plain steel usually refers to carbon steel because of the amount of carbon in it. For example, low carbon steel contains a maximum of 3% carbon in it. This affects the steel alloy properties and can affect the exact grade of steel the alloy gets. The plain steel we have in this selection is grade B7.

What is plain carbon steel used for?

Plain steel, also known as mild steel or carbon steel, is the most commonly used form of steel because of its low cost. It also still provides the material properties that work well for general purpose applications. You'll often see plain steel used in non-corrosive environments, such as indoors.
