Wedge rear hub nuts... (yes the big tight ones!)

[briantvr350i]

Hi Guys,

Can anyone confirm the size/thread of the hub nuts...
By reckoning they are M22 X 1.25... Making them metric fine.. But, my thread charts don't list a metric fine in that form... Anyone any better ideas. They couldn't be imperial could they?

Regards,

Brian(and a Red 350i)

I would doubt that they are metric, being the age of them etc

You could try RT racing as he list's them to buy

Hi Paul,

yes I know where to buy them... I want to know the size..

My experience over the last 8 years is that my '87 car has all sorts of fasteners both metric and imperial!

Metric nuts and bolts are (and were) much cheaper than imperial, need I say more.

Regards,

Brian (and a Red 350i)

No, you're right, they are 22 x 1.25. They are a non-standard thread, probably done by TVR on purpose. I doesn't even show up on any thread chart I've ever seen. And whoever thought it was a good idea to use a nyloc nut...

No chance of getting a die then?? I have a couple of drive shafts that I was going to refurb but one needs the threads running up with a die.

I got a couple of 'after-market' ones a few years ago... they looked suspiciously home-made...

22mm is 0.866", and a 1.25mm pitch would equate to 20.32 turns per inch - not any imperial thread I've ever come across, though I suppose if you were being generous you could call it 20 tpi which would make sense.
Nearest I can get to 0.866" is 55/64"... even that's 0.859375". So I think we can safely say it's metric.

With that diameter youd be better off with a chaser.

Hallo Guys,

The thread size for the big nut is 7/8" x 20

Tracy Tools are very good for taps & dies.

www.tracytools.com

They don't list 22 * 1.25 but if they exist they could find one.

They do list 7/8 by 20. (die £12 plus 20% P&P)

I'm sure that if you send them an old or new nut they will match it with a die.

I wondered that, but I thought it would be too loose?

GSX, ref your remark about things that age being Imperial: the Wedge cars are a mixture, depending on where they sourced the bits.
