What can happen if you use an oversized wrench on a nut?

Using an oversized wrench on a nut can lead to the wrench slipping off during use. This is because a wrench needs to fit snugly over a nut for effective torque application; if it is too large, it will not engage properly with the corners or flats of the nut. When the wrench slips, it can cause loss of control and possibly damage the nut or the surrounding components, as well as increasing the risk of injury to the user.

The other options, while possible in certain contexts, are less directly related to the issue of using an ill-fitting wrench. A nut may not break solely due to the misuse of a wrench, and while a bolt can be stripped under various conditions, that scenario is more related to the amount of torque applied rather than the size of the wrench itself. Similarly, using an oversized wrench typically does not make the job easier, as it creates complications rather than streamlining the process.
