I actually hate (not literally) Allen key button head bolts. Especially when combined with threadlock 😆. I’d recommend Torx for buttons. And anything that requires a smaller than 4mm Allen key should be torx too.
I’d say mostly you want 10-15mm screws. Then a handful that are longer. Also a few m6 screws too of varying length.
Washers for all the sizes you need, Stand off spacers are often helpful, and a bunch of nyloc nuts too. And loctite if you haven’t got it already.
