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.

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.

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

You definitely want those all filled up with some bolts.
A dab of your favorite lube will be fine to finger tight them too.
