Impact Wrench Sizing Guide For Automotive Work

One of the primary considerations when buying an impact wrench for professional automotive work is size. Since there are many sizes, it is advisable to pay attention to the size before buying that shiny tool. Here are some of the guidelines on how to buy an ideal impact wrench for your automobile projects.

Standard size impact wrench 

As the name suggests, a standard-sized impact wrench is what most users consider normal. It is ½ inches in size, which is an ideal size for most automobile projects. The size is also perfect for users looking for a standard torque level.

Which projects are ideal for standard-sized impact wrenches? The standard impact wrenches have many uses, and you can find them in any workshop and automotive shop. The main reason why you can get the impact wrenches with a torque level of 300ft/lbs is their ability to tighten up screws and nuts perfectly.

However, the normal-sized impact wrenches are not perfect if you want a torque level above the 300ft/lbs level. If you want more power, consider the bigger sizes. You can check also Best Cordless Ratchet Wrench

¾inches  impact wrenches 

The ¾inches  impact wrenches are bigger and more powerful than the primary option. As the name suggests, the size has a torque level of more than 300ft/lbs, which means more power on the nuts and screws.

While you can also find heavy-duty impact wrenches on most automotive shops, it is rare to find them in personal garages. You are not likely to see such an impact wrench in a private workshop because most people would not need such power.

When used in the right projects, the ¾ inches impact wrench is an ideal tool for heavy-duty projects, especially where power is needed. However, you should not get one if you are working on everyday tasks.

What Happens When You Buy The Wrong Impact Wrench For Automotive Work? 

It is easy to get confused and buy the wrong impact wrench size. If you get the wrong impact wrench, there are two possible outcomes.

A bad working experience

Whether you are a DYer or a professional mechanic, the last thing you want is a bad working experience. For example, working with a smaller-sized tool on a project that requires more power may overwork your muscles. On the other hand, a bigger-sized tool on a project that requires less power may force you to pay more attention to smaller elements, taking the fun out of a project.

Damages on nuts or incomplete work

If you work in a big-sized impact wrench on a smaller nut, the chances that the nut will over tighten are higher. You may also destroy the nuts by applying too much force. In the long end, you may incur some losses.

On the other hand, a small-sized tool may not tighten the nuts properly. In the end, you may have unfinished work, which is dangerous when working on automotive projects. Untightened wheels, for example, is the nightmare nobody wants to have, regardless if one is a professional or a DYer.

If you are uncertain about the best torque value, buy a primary tool. While you may be compromising on the working experience, you are guaranteed safety and an easier time tightening the nuts.


The use of an impact wrench is also an important consideration when working on automotive projects. There are two main sizes in this case: standard and heavy-duty. Each of the two options has different uses.

First, the price must correspond with the specs. If a tool has more advanced specs, the more it will be likely to cost. Second, it is wise to put into consideration the warranty. If a device has friendly warranty terms, you should not be hesitant to pay more on the price tag.
