Shimano Alfine Chainring Bolts and Nuts

I lost the chainring nuts and bolts for my Shimano Alfine crankset. Upon googling for "Alfine chainring bolts," I found this online store selling them. Unfortunately, they don't ship it to the US, but it states "Alfine have a size of M8 x 8.5 mm and are also compatible with older Tiagra, Sora and FC-CX50 5-arm cranks." Will it work as long as I find M8 x 8.5mm bolts? Or do I need a Shimano brand bolts (sorry if this is a silly question)? It would be nice if someone can point me to an online store that sells them, preferably in black. Thanks for your help in advance.

Preferably black? Stay away from aluminum bolts.

I've replaced stainless steel chainring bolts with titanium on a couple of my bikes. I have gotten them from Toronto Cycles which, sadly, appears to be closed due to the coronavirus problem.
These fasteners aren't terribly expensive, look nice and (most importantly for my "winter" bike) don't corrode.

Stainless steel on the left, titanium on the right.



Split image; SS fasteners on top, Ti on the lower half.

They are weaker than steel and more likely to corrode, gall, or seize than Ti. Same for aluminum nipples vs brass.
