I wouldn’t by 100 of any bolt for bicycle use. I probably wouldn’t by 100 of any fastener for home use.

About the only “bicycle use” only fasteners that I can think of are ones on the derailer that need a stop. Most everything else are 5M and 6M. Older bikes might use something less standardized but modern bikes (post 1995), there’s very few bolts that you can’t find replacements at you local hardware store.
Technically crimps are made in 2 sizes, for brake or shift cables, but the wider “brake” crimps certainly work fine for both.

so quick example and why I usually just buy in bulk.

https://www.homedepot.com/p/M5-0-8-x...4738/204283613 2 screws 1.31 plus travel and gas.

https://www.grainger.com/product/6HH...B&gclsrc=aw.ds 100 screws $11.28 not the cheapest source. just quick google examples.

The only other threading I'm familiar with is M8x1.0 (not the more common M8x1.25) used for square taper crank bolts and M10x1.0 for rear derailleur mounting bolts but neither of these are routinely replaced.
If working on vintage Id add M3 for dropout adjusters

I wouldn't trust the quality from an eBay seller. Especially for a critical component that has safety consequences, don't take a chance.

Belmetric is the go-to place for us car guys.

That doesn't mean others do not. Wrong to assume that no one should ever be breaking bolks, which may be more typical for a DIY that only works on just a handful of bikes their lifetime.

Even if a bolt never broke. missing is still a thing. I just got a surly fork in all the barnacles are empty holes.

Agreed.

You definitely want those all filled up with some bolts.

A dab of your favorite lube will be fine to finger tight them too.

I know you just want to get your digs in on me but you should really quote in context. The rest of my post was “That doesn’t mean that I lack a supply of bolts. They come in often come in handy. Racks and water bottle cages are the primary use.” I didn’t say, or even imply, anything like what you seem to think I’m saying.
