Sorry, didn't mean to mislead you. The rocker cover bolts on all the TC I've worked on were 5/16 diameter.

Bolts are sized according to to the nominal diameter of the shank, not the size of the hex head (wrench size). The rocker cover bolts are 5/16" bolts as the other posters have indicated.

I used a 11 mm wrench on my rocker cover bolts.
