Fasteners, screws, bolts, etc.

[RelishingPickles]

When changing out my engine air filters I notices the airbox screws heads were super rusted. I’d like to swap them out for new ones, but not really sure the best way to source them (or any other fasteners).
Is there some master list of all the fasteners used on these vehicles? Do I need to go to a dealership, or just any auto parts place? Is there a website that I could source them all from?
I’m in Canada, so that might add some complications, not sure.
Any advice appreciated. Thanks.

You could try a specialty fastener place such as brafasco or fastenal , both in Canada .

Ok, I know there is a fastenal near me. I'll just walk in and ask.

I was looking more to find out about the specs of each fastener though. Is there no reference?
What does everyone else do? just buy from the dealership?

Thanks

Replace your rusted fasteners with stainless steel fasteners.
I would also apply a little (very small coating) of a anti-seize compound to the tainless
fasteners threads for easy future removal.

My (singular and simple also JMO the best product) "go to anti-seize compound" I use on everything" made by LOCTITE, their NICKEL ANTI-SEIZE compound that is good up to 2,400*F compound.
