Threaded Rod

What is Threaded Rod? 

Threaded rod also known as "all thread" is a heavy-duty steel bar that is threaded along the length of the fastener. This trusty fastener makes fixing two materials together safe and secure. All thread is commonly used in many industries for general-purpose applications. It has a great reputation for pairing well with nuts, bolts, and washers to deliver a safe, secure connection between two materials such as concrete, wood, or metal. 

Threaded rod can be easily confused with different names it is referred to. Typically, if the rod is less than 12" long, it is called a stud. It is commonly sold in three main thread types. Each of these styles will have either a right-hand, left-hand, or left and right-hand thread direction.

Threaded Rod Styles Include:

  • Fully Threaded- Is completely threaded from end to end. 
  • Single-End- Only has threads on one end of the rod.
  • Double-End- Has threads on both ends that are either equal or unequal in length and an unthreaded section in the center of the rod. 

Right Hand Threaded Rod

The right-hand-threaded rod is typically the most common thread type. It is designed with threads that are configured in a clockwise rotation. 

Left Hand Threaded Rod

Left hand threaded rod is designed with threads that are configured in a counter-clockwise rotation. The left-hand thread is commonly used for situations where vibration may cause the right-hand thread to loosen.

Right Hand and Left Hand Threaded Rod

This style has right-hand threads on one end and left-hand threads on the other end of the rod. 


Uses for Threaded Rod

All thread is used for a wide variety of applications. They are especially beneficial for environments that experience corrosion. Additionally, they provide a clean, simple appearance once they are installed. 

Common Industries Include:

  • Construction
  • Electrical
  • Marine
  • Automotive

The Grade B7 plain finish threaded rod is designed for dry indoor use only.  The Grade B7 hot-dip galvanized fully threaded rod provides more corrosion resistance making it suitable for exterior use.
