Front spindle thread.

[R0B]

Can anyone tell me the thread pitch? Thanks.

I’ve just measured the pitch at 1mm and the od of the spindle at 17.9.
I’m going for M18x1.

[R0B]

Just done an Internet search is coming up with M18x1.5 pitch could this be incorrect?

[Forden341]

This nut on eBay is listed as 18x1 and the one I measured was 1.0 as measured with a thread gauge.

What’s your plans with the spindle? Is it damaged?

[R0B]

Thanks. The nut will go on three turns and no further I don't want to screw it on any further, as I don't want to cause more damage. This is on a factory power steering spindle and they are like hens teeth.

Blimey. Those nuts on ebay are £25
£3.60 from Brickwerks.

Cheap dies are available for around £15, either that or a thread file if you are careful.

If it's just picked up a slight gall, it's probably safer to use a file to clean the visible damage up than running an untested cheapo die down the whole thing.
Doesn't necessarily have to be a thread file - a V shaped needle file will work fine, too. If you colour the whole thread black with a permanent marker (or engineers blue if you're posh) then wind the nut on by hand giving it a few bites at the stiff bit, you'll be able to see fairly clearly what's holding you off
