The adjustable wrench is found in almost every toolbox, but few people really know how to use it properly. However, improper use can damage your nuts, bolts, and even the tool itself! Think you’re doing everything right? You might be surprised. Here are the most common mistakes and tips for using your adjustable wrench like a pro.
1. Using it as a fixed key: a classic mistake
You might think that an adjustable wrench can replace a flat wrench … Wrong! Unlike fixed wrenches, it doesn’t offer a perfect fit, which can damage the nuts and the wrench itself. Overtightening can also deform parts.
The solution? Adjust the opening carefully to reduce play and avoid using it for tightening operations requiring high torque .
2. A loose jaw: watch out for damaged nuts
An improperly adjusted adjustable wrench can quickly round off nuts and make them impossible to unscrew .
Tip: Take the time to tighten the adjusting screw so that the jaw fits snugly against the nut faces. Just a millimeter of play can be enough to slip and damage your part.
3. Do not use it on screws that are too small
If you’ve ever tried to use an adjustable wrench on a tiny screw , you’ve probably noticed a lack of grip .
Why? The design of the tool does not allow for optimal grip on very thin elements .
Solution: In these cases, use a flat wrench or a suitable socket instead .
