Best Torque Wrench for Your RV: Our Top Picks

If there’s one tool any full-timer, snowbird, or even a vacation RVer should always have handy, it’s a torque wrench.

In general, highways and interstates are full of dips, potholes, and other nut-loosening factors that will wear on certain parts of your RV. As you travel, you will need to keep certain things such as wheel lug nuts, hitch bolts, and suspension hardware tightened.

The best torque wrench will allow you to prevent premature wear and tear on your RV. And, it will save you from catastrophic, life-threatening events such as a wheel flying off or your trailer unhitching.

So, what is this essential tool exactly?

Explaining the Basics of the Best Torque Wrench

A torque wrench is a tool you can use to tighten nuts and bolts to a predetermined torque value. With this instrument, you can tighten fasteners to the proper tension. This detail is essential to help avoid damage from over tightening or joints coming apart from under tightening.

In other words, applying the correct torque measure is crucial for safety, assembly, and the performance of your RV’s equipment.

What is Torque?

Torque represents the measure of how much force on an object causes it to rotate, with the pivot point serving as the axis the object rotates on.

Pound-foot or Foot-pound?

Now I know what your thinking.

Surely I must mean foot-pound not pound-foot.

This notion is actually a widespread misconception that even tool manufacturers are guilty of perpetuating.

Be that as it may, foot-pound and pound-foot represent two completely different measurements.

Notably, pound-foot represents a unit of torque and a vector measurement created by one pound of force acting on one foot lever.

On the other hand, foot-pound (or more accurately foot-pound-force) represents a measurement of work. Work is the measurement of force over a set distance.

In other words, one foot-pound-force is the amount of energy needed to move a pound object one foot of linear distance.

How a Torque Wrench Works

Torque wrenches are first calibrated to apply a specific amount of torque to a fastener. The amount of torque applied depends on the amount of force on the tool’s handle as well as the length of the wrench.

The formula for torque is force x length.

Inside the handle is an internal mechanical indicator which connects to a calibrated scale. Once the indicator senses that the desired torque has been reached, stop twisting the bolt. Tools will typically have an easy-to-read scale or display to show how much torque is being applied.

The best torque wrench models allow you to calibrate to read in pound foot (lb-ft), pound inch (lb-in), or newton meter (NM).

The Different Types of Torque Wrenches

Now let’s look at some of the most common styles of torque wrenches that you will find in the garages and toolboxes of most RVers.

The four most common types are electronic, beam, click, and dial torque wrenches.





How to Use a Torque Wrench

Before you begin, it’s vital to make sure the torque wrench is calibrated. If it is, the tool will often display a sticker indicating that it was.

Most torque wrenches will have a lock which you would need to disengage before you can rotate the handle. Once the lock is disengaged, turn the handle to line up the number on the handle with the center line on the barrel.

You can choose to increase or reduce the torque by turning the handle clockwise for more torque or counter-clockwise for less.

After you finish adjusting the torque, re-engage the lock to avoid altering the setting accidentally.

When using your torque wrench, always use one hand to hold the pivot in place with the other on the handle. Rotate the tool until it makes a noise (usually a click).

This aspect is important:

As soon as you hear the noise, stop turning, because one click is all that you need. If you turn again, you will probably overtighten.

Once you’ve finished, position the scale back to its lowing setting, to prevent messing up the accuracy of future measurements.

Also, try not to use them on fasteners which are already entirely tightened with a standard socket or wrench. If you do, you may exceed the correct level of torque. Instead, it’s better to completely loosen the fastener then re-torque it to the correct setting.


Even the best torque wrench models need regular calibration if they are to continue providing accurate and reliable measurements.

Calibration is checking the precision of a measuring instrument, as well as adjusting to align it to the standard. It allows the tool to produce more accurate results throughout the tool’s lifetime.

Measuring tools such as torque wrench become less accurate over time without regular calibration.

The permitted frame of calibration error is five percent, with any error beyond that number potentially damaging the tool’s performance quite severely, thus resulting in product failure.

You can use a professional service to calibrate your torque wrench or do it yourself.

Here’s how:

Please note, that we do not encourage folks to use their torque wrench as a breaker bar (not ratcheting wrench used to loosen stuck fasteners). Using your torque wrench instead of a breaker bar will throw off the calibration and damage your tool in the long run.
