Tap thread size for...

[Wobba]

...the two big bolt holes in the stub axle for the brake calipers? Maybe M10x1.5? I can't tell...

Need to repair the thread in a W3 stub axle that Leighanne has lent me, seems it was threaded in the past. Be a shame to throw it away.

Pfft. You guys suck.

I think it is 12x1.0m tap size.

Standard for M12 is 1.75mm pitch. Fine can be 1.5 or 1.25 I think. I suppose they it could be a totally random custom size though.

If you have a bolt and die you could check it by putting them together like nut and bolt.
