They’re some weird size. I think 1/8” works but you should test before you leave the store

did a quick search and they call Futures a 10-24 Grub Fin Screw
also, another site says:
The screws come in two sizes, 3/32 10mm (future fin system) or 3/32 8mm (fcs2 fin system).

So, it sounds like you have the right size 3/32, but length depends on Futures or FCS
