Threaded rod

A Guide to Threaded Rods:

On construction sites, threaded rod is known by a variety of names, including all-threads, threaded bar, screw rod, stud-bars, threaded studs, or simply studding. Basics of a threaded rod, what are its purposes, types of threaded rods, common threaded rod finishes, common sizes and cutting threaded rods are all covered in this blog. 

What is Threaded Rod?

Threaded rods, as the names suggest, are rods that come in a variety of lengths and are threaded along their whole length.

Threaded rod, which looks like a hex set screw and comes in a range of types, lengths, and finishes, is one of the most versatile products for giving a secure fix and allowing other fixings such as nuts and bolts to be secured to it.

Uses for Threaded Rod:

Threaded rods are commonly used to hold two items together when a longer and more stiff fastener than a conventional bolt is required. They can be used to bind wood or metal pieces together, as well as to add strength to concrete and other material-supported buildings. Because of their threading, it’s simple to attach nuts and other fasteners to the rod as needed.

Threaded rod is consequently ideal for supporting or hanging goods such as piping, cabling, and ductwork from roofs and ceilings, making it popular in construction. Threaded rods are commonly used in MEP and HVAC applications to provide a stable fastening for support systems because they can resist extremely high levels of pressure and stress. Threaded rod is used to fasten items in a variety of industries and comes in a variety of types, lengths, and materials.

  • Medical machinery
  • General construction
  • Automotive assembly and repair 
  • Electrical installation
  • Marine applications
  • Heating and ventilation installation
  • Engineering
  • Plant room maintenance
  • Agricultural 
  • And so on. 

Threaded rod functions similarly to ordinary bolts and screws, making it straightforward to use for anyone who has worked with other types of large fixes. The procedure for installing a threaded rod is fairly similar to the procedure for putting a bolt or screw. Although there are some distinctions, threaded rods are typically longer than ordinary bolts and lack a head for hammering or driving.

Types of Threaded Rod

There are several types of threaded rods that you will see online and in the physical market and you can easily find one that suits different applications and conditions.

A threaded rod is usually supplied with a right-hand thread (where a clockwise rotation will tighten). It can, however, be supplied with a left-hand thread for instances where a right-hand thread might loosen due to vibration.

The most frequent type of threaded rod seen in construction is all thread (or completely threaded), because the thread allows for full engagement of nuts and other threaded fasteners.

Because the threading provides strong resistance, it can also be embedded in materials like concrete.

Tap-end stud bolts and double-end stud bolts are two further forms of threaded rods. Tap-end studs have different thread lengths on both ends, but double-end stud bolts have the same thread length on both ends.

Although there are fine threaded rods with threads that are thinner and closer together than the regular variety, most threaded rods will have a standard thread.

Fine threaded rods have a higher shear and tensile strength, making them less likely to loosen, which is important in installations that are subject to vibration.
