They're not so cheap that you can just buy them when you need them. They're so cheap that you can keep them in stock! Totally agreed about how annoying it is to lose days to shipping time for trivial purchases though.

Having stock of everything you may one day need is going to require a lot of space though. I used to have about one grab bin full of all of the most commonly used metric and imperial sizes nuts and bolts (and only with hex heads) in my metal working shop and that already took up quite a bit of space.

  Having stock of every possible type of M3 screw/nut you could ever need does not take up a lot of space and also doesn't cost that much. $100 and it'll feel like you have a lifetime supply of every possible type you'd ever need and because of the time saved over the course of your life (and inflation) it'll definitely be a sound investment. What does take up space is the part of your brain where you thought you had knowledge of every possible type of M3 screw/nut you could possibly need. After a few years of owning a "massive" collection of M3 screws/nuts that part of your brain will expand by an order of magnitude and suddenly you'll be looking to stock up on something like, "tapered torx head, alloy 18mm M3 screws" and maybe even nylon M3 screws/nuts. Example: A few years ago I needed a square M3 nut to go into a 3D printed part. "No problem", I thought. I have plenty of square-shaped M3 nuts. Except the square nuts I had didn't fit in the part! "What the heck? Why is the slot for the square nut so thin‽" Turns out there's a standard for thin square nuts, DIN 562 where the thickness of the nut is 1.8mm instead of the usual 2.2mm and I didn't have any of those. Now I have a little baggie of 50 M3 DIN 562 nuts (well, probably ~40 remaining) that is carefully marked separately from my other little baggie of regular M3 square nuts and I know better than to think, "I have all the types."

    True, small stuff doesn't take up a lot of space. But bigger stuff does and it really adds up. Hm, I didn't even know about the differences in square nuts, and I've been around the block a couple of times. Thank you for that new bit of knowledge. In return: setscrews... don't get me started on those. There are so many kinds, shapes and sizes that's a whole new category. And all manner of driver bits, I have so many of them I need to organize those too...

      Three minor but frustrating differences that have caught me have been cosmetic issues, which don't really matter until they do. I bought screws from a company for several years when suddenly they changed the head by adding some knurls to M3 socket head screws. A different set of Truss head screws had a small countersink type feature added around the torx drive. And then the finishing process changed. All subtle changes but when one screw out of 20 is different it stands out. My solution was to track batches of cosmetic screws and compare them before transitioning to the next batch. Leftovers go in a spare parts bag.

        Interesting, what kind of workpieces do you make that you put that much attention to detail? Are these for display? Or is it just very high level of workmanship applied to otherwise normal articles?

        This was for occasionally handheld measurement instruments. Ultimately it might be a little nit picky, but I figured if it was noticeable to me it might be noticed after a while by a user and then bother them. Some users would never notice but why risk it? While thinking about what to do I went down a rabbit hole learning about clocking screws. I decided that was far from necessary but if I ever make something really nice for myself in metal with the right design I might give it a try. https://blog.lostartpress.com/2019/04/18/the-church-of-the-clocked-screws/ https://blog.lostartpress.com/2019/04/18/the-church-of-the-c...
