Does anyone know the specs/ measurements of standard 164 wheel studs, I assume 200 studs are the same.

I would like to replace them but will be going longer and probably metric thread.
This may be correct?

They're not stamped or marked with anything. I'll take a couple of pics an post them up.
I'd guess they're an inch longer than the standard ones, hopefully I have a spare 240 stud floating around the place that I can measure.
Front studs are longer than 140 front studs on account of thicker disc. That's all I know
Nothing I can find has a knurl diameter that size

Did you have any luck checking those other ones out @AshDVS ?
Apologies for my slackness, here you go -

I think 164 studs are the same as 240 studs, the one pictured above looks the same to me, but I'm not totally certain.
To my untrained eye I agree with Angus

I think you are both correct.
A quick bit of research on the FCP site might confirm, look up studs for a 240 and for a 164 and see if the part numbers match.
Non-Gen catalogue says they are the same.

Now I need to find some of those long ones, any idea where they came from?

I would be interested in yours @Ash but the spacers are no good to me and it putting the spacers on the shelf seems like a waste of money...
