Anyone know what thread these are? Seem to remember they are either m10 x 1 ?

Oops meant to say M11x1, anyone confirm?

M11 x 1 Get some ARP bolts off ebay. Then you know you are buying quality that will not fail on you. About £25.

I would but its for a bloody Tiger flywheel and only caphead bolts will do, i know they have lnown about this design flaw in their lightened flywheel for years and have still done bugger all about it, told the owner to get them off burtons, nearly a fiver each!!!
