Did you know that you can seriously damage some parts of your car if you use an impact driver instead of an impact wrench. What is the difference between an impact wrench vs an impact driver? After you read this you will know the difference and be able to save yourself from causing damage to whatever it may be that you are working on.

First and easiest way to tell the difference is the size. When you see an impact driver they are typically shorter in length and a little more bulky. When it comes to an impact wrench they are typically longer due to them needing leverage to turn, where as the impact driver is made to fit in smaller spots and "drive" the bolt or screw.

Most impact drivers will have a setting on them that says "hammer". This is the setting that you would put it on when you need added penetration with the turning ability. This allows the screw or bolt to be slightly tapped in as it turns. Like a little jackhammer. Using this impact driver on a fragile car part or soft metal can cause severe damage. That is why impact wrenches have no "hammer" function.

Most impact wrenches have a setting for torque. This means you can use it for the added power and make it easier on yourself without the worry of adding to much torque and breaking something. Impact wrenches are made for getting a nut or bolt of with ease and mainly used in the automotive field. They have the ability to add force to the turning of a nut or bolt. This being pretty much the opposite of an impact driver.

Next time you get a tire fixed listen to the sound of the impact wrench as they use it. the tapping you hear is the wrench tapping sideways to get the lug nuts off. For an impact driver, they are most commonly used when working on wood to get those big long bolts through. As with other tools you can find these both cordless or electric. You can also get an air impact wrench or air impact driver if you really need some heavy duty stuff. So next time, before you go slapping a battery in and a socket on and going at it, make sure you know what you are using and avoid costly mistakes. A little bit of information can go a long way if you put it to good use.

Happy wrenching!
