Mk1 GT3 sport design rim bolts

[ArcticGT3]

Can anyone tell me definitively what size and material bolts are used in these ?

I've bought a spare to experiment with but it's already been split and stripped with the bolts missing.

Thanks for the replies guys, are they stainless or Titanium ? Titanium is suggested by a few online retailers as being for OE Porsche/Jaguar which seems a bit overkill, I guess it's to avoid a reaction between stainless and the alloy ?

I'll get a spacer of some kind and torque each hole gently to test the threads ??

Nothing's ever straightforward is it, I can see me just throwing it in the loft incase I bend one of the ones on the car

Cheers rick/Slippy got hold of some with the exact same markings on but still no idea what they'd made from. Makes no odds really.
