Bolt size for blast city cp?

[tzakiel]

Does anyone know what mm these hex bolts are? I need to take a wrench with me to somewhere and want to carry the right one.

Also I have heard these are easy to break when trying to remove. How can I minimize the risk of that? Are there commonly found replacements available?

I can't remember but you should be able to find it in the parts list and/or manual on the Wiki:

I didn't have any issues removing them when I had a Blast. Just make sure you use the correct socket and go easy. It should just be a standard metric bolt with a large washer head so should be straightforward to replace if you have to.

I think they're some weird imperial size, because 9mm is too small and 10mm is slightly loose. However, I've opened mine with 10mm.
