Use coins to close the gap on a too-narrow bolt
Visualize the setting: you’re getting ready to work on a do-it-yourself project, and your trusty wrench is at the ready… but you discover that the bolt is too narrow to be grabbed with the wrench.
Don’t just use it as an excuse to give up and watch some TV instead. The answer is as straightforward as rounding up loose change. Simply insert coins into the space between the wrench and whatever you’re trying to pick up, filling it as much as necessary.
