its 1.00 metric as ive checked a spare i have against my tap and die

but my tap only has 1.00 / 9mm and the bolt is fatter than 9mm

take the axle to a fastening supplier and they will be able to tell by sight , get a couple of hardened bolts or cap head bolts and some washers that fit in the arms

itl probably cost about a quid  :)

I have Primo power bites and bought a Ti spindle and found it had different size bolts, managed to get some, my local bike shop got some from Billy's bike store I think.
