Pro taper Allen and nut size

[polaris6]

Can anyone tell me the size of the nut and Allen that hold the pro tapers from rotating forward or back? Last year they would get loose and I want to pack the appropriate tools.
Also what would be the "must" size wrenche to bring on trail.

Many thanks

10mm wrench and 5mm allen I believe.

Everything on the Pro is metric just FYI, no more guessing if its standard or not... I would carry metric stubby wrenches 10mm-17mm, metric allen multi tool, torx multi tool, vise grips, phillips and flat head screw drivers, crescent wrench, etc... Better to be prepared...
