Difference between a manual torque wrench and impact wrench

Impact Wrench vs Torque Wrench, both the impact wrench and the torque wrench share one feature: the primary function. This function, of course, is to tighten and/or loosen fasteners like nuts and bolts.

Both impact wrenches and torque wrenches serve this purpose, but there are some significant differences between the two tools. These distinctions are significant enough to persuade you to select one of the devices over the other.

This impact wrench vs manual torque wrench comparison will explain what torque wrenches and impact wrenches are and how they differ.

What Is A Torque Wrench?

A torque wrench is a hand tool used to apply precise amounts of the rotational force (or torque) to nuts and bolts.

When a fastener needs to be properly tightened, this device is used. A torque wrench has a scale engraved on it that indicates how many foot-pounds (ft. lbs) of torque are required to tighten a specific fastener properly.

The torque wrench can be calibrated, typically from 10 to 100 ft. lbs., by twisting the handle so that the collar rises up the tube until it highlights the required force (in ft. lbs.).

So, if you're tightening a lug nut that requires 25 ft. lbs. of force, calibrate the torque wrench to 25 ft. Lbs. on the scale.

The ratchet wrench is attached to the other end of a torque wrench.

What Is An Impact Wrench?

An impact wrench is a type of power tool that is used to loosen or tighten lug nuts and fasteners. It is well-known for producing a high torque output with little effort.

Impact wrenches are typically powered by compressed air, but electric and hydraulic power sources are also available. Cordless electric impact wrenches have also grown in popularity.

The motor of the impact wrench twists the fastener in short, sharp bursts (about every five or so seconds). This continuous and forceful (or, if you prefer, impactful) twisting at short intervals is what eventually loosens or tightens the fastener.

Consider it like a tiny hammer hitting the fastener repeatedly until it tightens or loosens.

Impact wrenches are classified as cordless, corded, or pneumatic. They also come in a variety of sizes, including 1\4 inches, 3\8 inches, 1\2 inches, 3\4 inches, and 1 inch.

Impact Wrench vs Manual Torque Wrench: How Do They Differ?

Now that we have a better understanding of how each of the two tools works, let us look at how they differ from one another in detail.

How They Operate

The most significant distinction is that impact wrenches are power tools, whereas torque wrenches must be operated manually. This means that the latter requires far more physical effort on the part of the user than the former. In fact, you could work with an impact wrench all day without getting a sore wrist.

The precision of Torque Control

In addition, with a manual torque wrench, the user has more precise torque control than with an impact wrench.

Noise Pollution

If noise is an issue for you, a manual torque wrench is a better option because it is soundless in and of itself. Impact wrenches, on the other hand, are loud and may be harmful to your hearing. This is why it is recommended that you wear ear protection when working with an impact wrench.

Price

Because of their manual quality, torque wrenches are much less expensive than impact wrenches. This is not to say that impact wrenches are expensive; their prices vary depending on size and type, with cordless impact wrenches being the most expensive.

Advantages Of Torque And Impact Wrench

All of that being said, let us take a quick look at the advantages of each of these two types of wrenches.

Pros of an Impact Wrench

Because of its automatic nature, an impact wrench is a much more powerful tool. Because of the same feature, it is also much less time-consuming to use. Impact wrenches require very little physical effort from the user, so using them all day will not tyre you out.

Pros of a Manual Torque Wrench

Because it is a manual tool with no motors, a torque wrench is virtually silent. It is also the less expensive of the two types of wrenches. One of the main benefits of a torque wrench is its ultra-precise torque control, which allows for the perfect tightening or loosening. Torque wrenches can be useful for maintaining bicycles.

Verdict: Which One to Go For?

Which should you choose now that you understand the functions and differences between manual torque wrenches and impact wrenches?

Your choice should be based on preference as well as the utility of each tool in relation to the task at hand.

Manual Torque wrenches and impact wrenches may have similar functions, but they serve very different purposes.

While impact wrenches are ideal for loosening or tightening lug nuts, frozen or rusted fasteners, and large bolts, torque wrenches provide the user with torque control in situations where fastener tightness is critical.

Keeping in mind the differences mentioned in the previous section and just before this, we hope you will be able to successfully evaluate your wrenching needs and purchase the right tool for yourself out of the two.

Of course, it is recommended that you own both impact and manual torque wrenches because, as we have seen, they serve sufficiently different purposes to justify purchasing both.
