lol, mcmaster carr is probably one of the only specialty e-commerce sites that anyone will randomly bring up in UX discussions or hobby conversations. everyone loves mcmaster carr, like actually everyone, so yeah, lots of people who haven't read this already independently decided that mcmaster carr is great.

even if you're not going to buy there (their prices are high, compared to alternative suppliers, is what I've heard, and there are items and brands they don't carry) it's still a super useful reference of what's possible and what general solutions in that area look like and cost, or even just basic lookup for what types of nuts and bolts you should look for in a project. like it's actually just a really nice pleasant interface for working with hardware in general.
