Walnut shells are for removing paint off something you don't want the actual material finish to change on.
Bead blasting will alter a parts finish -- and the walnuts or plastic media will just clean things without that resulting in an altered finish.
"Tumblers" are normally used for deburring and or polishing parts... although, I guess, with the right media they can be used for cleaning too.
The problems come with cleaning small parts - or any part - with something that will or does remove the parts original plating etc -- and you end up with small parts that used to be zinc or cad plated - that now RUST within a week because they're now just bare steel.
Personally I toss old fasteners into the scrap bin and replace them with new stainless steel or the correct Grade hardware for the job. I figure my time is worth "something" (although the wife thinks differently). And when restoring or building a car I want the final product to be up to snuff. I DO spend an awful lot of time polishing small button head stuff.... but I got a kool tool (Polishing Grip) from a buddy of mine (Timmy Diver) that makes this pretty quick and saves my fingers!
