Use many pennies to buy a washer or use one penny to make a washer
Boing Boing: "Tom Parker, author of Rules of Thumb, created a washer out of a penny instead of spending a lot of pennies to buy a washer."

That is awesome and total out-of-the-box thinking. It is a little ridiculous though that it is cheaper to use a penny as a washer than buy an actual washer.
While financially it might make sense to make your own washers out of pennies, if you factor in the hourly rate you're paying someone to drill holes in all the pennies and the time it would take to find the pennies, machine matinence, etc. it's probably cheaper to just add washers to your materials order. - Maddie Regan
So the next question is what is a home-made penny washer rated for in the industry? I would imagine that its a bit weaker considering it is not intended to take much stress other than the everyday wear and tear of sitting in someone's pocket.
True, while pennies have a Moh hardness of around 3, steel is closer to 7. Canadian pennies are actually only 1.45mm thick, so they are quite thin compared to the common washer. Probably best to stick with regular old washers, not to mention that playing with too much zinc can be a health hazzard.
This doesn't seem like the most practical idea for a stock of washers. However, if you are one or two washers short in whatevery project is happening then by all means, go for it. Only, be careful with this sort of thing since I'm pretty sure it's illegal. I could be wrong, but in the back of my mind I remember hearing something about it being a crime to destroy money (even money that is practically worthless).

I don’t believe that this is practical at all and if they US Mint wanted to they could claim fraudulent intent and punish someone, but hey its fun!
