The Best Beam Torque Wrench
Beam torch wrenches are preferred to the newer clicker types because they’re easier to use, cheaper and more accurate. Provided you take care of them they’ll also last a lifetime.
On this page, we will try and find “The Best Beam Torque Wrench” for you. We’ll also examine what makes a good beam torque wrench and discuss some of the pros and cons you need to know.
What is a Beam Torque Wrench?
A beam torque wrench is the simplest kind of torque wrench. It uses circular force for the tightening or removing of a nut or a bolt. A beam torque wrench consists of three parts: the main beam, a pointer, and a scale. It is an essential tool for small automotive engine repairs.
The torque is usually measured with the help of scale attached with the beam torque wrench. This tool helps to ensure that engine part, such as cylinder head blocks, are tightened with the ideal tension. To help an engine last longer, it is important that the nuts and bolts are tightened precisely.
Advantages and Disadvantages of Beam Torque Wrenches
The beam torque wrench is cheaper, easier to use and extremely accurate. It’s also a great wrench for bench-top work.
The problem many find is you have to always read the scale. For the most accuracy, your eye should also line up directly with the guage. When you are working on something you can’t actually see (which often happens with car repairs) a click-type wrench is better.
Here’s a summary of the advantages and disadvantages.
- It is a simple, reliable and proven design to measure the torque precisely.
- It can measure torque accurately in both directions.
- It can easily be used to measure torque from zero to maximum torque.
- The accuracy of the beam torque wrench is as high as 2 percent.
- Sometimes requires maintenance for accurate measuring.
- The Scale needs to be constantly watched to ensure accuracy.
How to Use a Beam Torque Wrench?
Using a beam torque wrench is much simpler than other types of torque wrench. It works essentially like a fish scale. As you tighten or loosen the fastener, a beam in the wrench’s head shines back at the gauge. Following the steps below can help you understand the right method.
The first thing to do is to check if the scale shows zero or not. Next, consult the tool owner’s manual to determine the precise torque require for the bolt, and input the measurement into the wrench scale. It is important to consult the manual as it will help you to determine how much torque is appropriate. Applying too much torque may result in the damage of the bolt.
Now you need to attach the socket to the bolt for tightening or loosening. If you are tightening the bolt, turn the wrench handle in a clockwise direction. For loosening the bolt, turn the wrench handle in the counter-clockwise direction. Once the required amount of torque is applied then you must stop immediately.
Maintenance and Calibration
Provided it’s well cared for, a reasonable quality beam wrench should be accurate for life. They have an inbuilt accuracy and being far simpler to operate than click-style wrenches, there’s less to go wrong. A beam torque wrench only needs replacing if you have severely overloaded it and bent the shaft or bent the beam.
Something you may encounter is if the gauge doesn’t return to zero after use. If this happens, bend the indicator and line it up with the pointer at the end. Center it with the “0” on the indication scale.
