What size are head bolts? 14 mm?

manual says 10 x 1.25mm but i dont understand that but the good thing is that the bolts strip the socket instead of stripping the bolt ./ thats a good thing, i undone mine with a 12point socket 2 so its all good

The head is 14 mm 6-point. The bolt is a special 10 x 1.25. Metric bolts are sized by the diameter of the shank and thread spacing, not the size of the head. Why are you asking? The factory bolts are very tough.

Yep, 10 X 1.25 metric thread.
These head bolts can only be purchased from the Honda dealer at about $6 & some change for one.

The head bolts are tough & can be re-used unlike TTY (torque to yeild) bolts which require a torque angle meter.
