Mexican Wrench

Using the wrong tool for a job. Most often used when trying to use a pair of pliers or vice-grips to remove nuts and bolts.

I didn't ask for a mexican wrench, go grab me the correct tool.

mexican speed wrench

In its most literal form, any member of the wrench family featuring a screw-adjustable aperture, allowing one wrench to fit any sized nut or bolt. While not the ideal tool for the job, the mexican speed wrench is the fastest.

Is that bolt there a 15mm or 16mm? Ah, fuck it. Hand me the mexican speed wrench.
