You can usually just flip the back of the bolts around, this will allow them to tighten down on the chainring. Obviously looks a bit shonky but it does the job at a pinch.

search ebay for "singlespeed chainring bolts", there's tons and tons starting at about a fiver for 5. all colours, Ti ones for around a tenner a set too.
thanks folks...do i need those tabs as well?
Unless...you're buying a 30T ring that is actually threaded, you can just use the existing bolts, well half of them.
You would use either the tabs or the bolts I think.

No, either shorter bolts OR shims.
EDIT: Damn, too slow.
e13 30 tooth ring
don't know about that ring, but the on-one ringmaster nw ring was so thick that regular bolts fitted perfectly.
Unless you are in a hurry, get the ring then try regular bolts (the right way round) and if they are too big, then get some specific single ring bolts.
