Are chain ring bolts a common size?

I need to replace a chain ring and a bolt after this.



I've managed to order a chain ring but am struggling for the bolts. Are double chain ring bolts a standard size? It's an FSA Omega crank but the rest of the drivetrain is Shimano 105.

Yes, thanks. Appears that there are standard dimensions. I'll 'borrow' one of my other bike and then order a set from the usual place.

Cheers!

Got to ask - how the hell did you mange to do that?!

No,Pablo was right. The bolt went missing after the Grizedale Grizzly CX ride a few weeks ago and I never quite got round to replacing it. Then riding home from work last week, I accelerated out of a junction and whoops!

All sorted now though thanks. I borrowed a bolt off my old road bike and it fits so now I can buy a new set off Wiggle. It was something neither Halfords or 2 LBSs sold!
