need bolt size

[Target30]

anyone know the thread size of the nut for the swingarm bolt? i cant tell if i have stripped out the end, or am just using a nut that is too small, i really dont want to pull the swingarm bolt back out again! i meant to bring the one i had to work with me, to buy a couple different sizes on the way home, but i forgot it!

T30,
You neglected to say if this is the standard 3HE swing arm bolt or a modified version that goes with the later series swing arm .
If it is bog standard 3HE FZR 600 it is14.00mm diam by 1.5 mm pitch.

22 mm for outside not sure about inside

Axle nut is 22, swingarm outside is 17.

George's answer sounds right. I would have said 12 or 14 off the top of my head.

Guys,
to keep this so we all understand :-
the axle nut is 22a/f (ie across the flats of the nut ) NOT AF by the way which denotes American fine thread

The problem lays in that a nut of 8mm diam * 1mm pitch can have 12 a/f or 13a/f depending on the manufacturer.

PS it better be right cause

A} I used a digital metric caliper on the bolt diam
and
B} then used a metric pitch guage on the thread Nerd
