What hex wrench size do I use on my Flair 58?

I lost the allen key/hex wrench that my Flair came with, or need a different one to adjust an alternate part.

The Flair 58/58x uses multiple bolt types, and therefore, a different hex wrench size will be needed depending on the part that needs adjusting: 

Base bolts and main portafilter base bolts – 5 mm (included standard with your unit) 

Secondary portafilter base bolts – 4 mm

Lever, lever hook, and ball set screw bolts – 3 mm (lever and lever hook benefit from the use of 2 wrenches, so that you can adjust each side simultaneously)

Cam ramps to lock in portafilter – 2.5 mm
