Cutting a Threaded Rod

Cutting a threaded rod is tricky especially if you want a smooth end. A well-cut threaded rod will enable the hex screws to turn cleanly towards the threads. This is the reason why it is important to know a few tips on how to properly cut a threaded rod.

The old way of cutting a threaded rod is through the use of a hack saw. This simple method, when done properly, is the most effective way to cut a threaded rod. But you could also use power tools such as a circular saw or an angle grinder to cut a threaded rod. Whatever the case may be, here are the simple steps in cutting a threaded rod.

Tools and Materials Needed:

  • Vise or table clamp
  • 4 pieces of hex screws (according to the size of the threaded rod)
  • Hack saw or angle grinder
  • Tape measure

Step 1 – Determine the Correct Length

Use a tape measure to determine where to cut the threaded rod. You only have one chance of doing this right so pay attention to the length of the threaded rod.

Insert two pieces of hex screws and let run along the threaded rod. Turn the screws at least two inches away from the cutting point. Turn both the screws on opposite directions to tighten.

Next, insert a pair of additional screws and secure at least an inch after the cutting point. These screws may serve as ideal holding points for a wrench or vise grip to prevent damaging the threads of the rod.

Step 2 – Secure the Threaded Rod using a Vise or Table Clamp

Place the threaded rod on the table and secure with a table clamp. The cutting point should be at least 12 inches from the edge of the table. If you are going to use a vise with metal jaws, then it would be best to place small planks of wood in between the vise jaws to prevent damaging the threads on the threaded rod.

Step 3 – Cut the Threaded Rod

Grab the hack saw and carefully make a mark on the cutting point. Carefully saw the threaded rod to achieve a smooth cut. You may use pliers or a vise grip to grab the end of the threaded rod for added leverage. Just make sure to grab the pliers by the hex screws installed on the threaded rod.

You may also use a circular saw to produce a smooth cut. Remember to take the necessary precautions when using power tools and wear appropriate safety equipment as needed.

Step 4 – File the End

Use a file to smooth the ends of the threaded rod. Remember to file the ends in a straight manner. This will help prevent thread damage as well.

Step 5 – Turn the Screws to Clean the Thread End

Loosen the screws and turn until the end of the thread. A smooth thread end will enable you to remove and install the screws with no extra effort. Try removing and installing the hex screw a couple of times to clean the ends of the thread.

Cutting a threaded rod can be done safely and more efficiently with the steps provided above. Remember to work in a well lit area to produce an even cut.
