I've got an old school Race Face Turbine five arm crank with Middleburn 'rings.

My Shimano chainring bolt tool is too wide to sit in the chainring bolt slot.

Is there a smaller diameter tool?

I'm reluctant to do that as I've owned it for nearly thirty years.

I recently purchased the park tools version, it's double ended and each end is a different size, so I can believe that there is more than one size of chainring bolt.

@stayhigh - when the same happened to me a couple of years ago I got M-Part bolts which have hex profiles on both parts. HTH.

I sprayed some penetrating oil on em and then used circlip pliers to hold the back of the bolt while I turned the Allen key

Big screwdriver is my normal tool, as long as the bolt hasn't gone all the way through obviously.

Get some metal from the shed and fabricate one its easy. If else big screw driver or a kitchen knife.

Just come back from a ride. Came across a young lad with a brand new Inbred which had dropped two of its chainring bolts! A bit shoddy I thought........and a long walk back for the lad.
