Cannondale Carbon SI Crank BB30 Axle bolt size?
 

2006 Cannondale Synapse Carbon 3 with a bb30 carbon si crank set.
The crank bolts (2) are ruined and the threads in the axle need cleaning out. What size tap? 1.0mm pitch x diameter? My thread gauge matches up to 1 mm pitch. I like to know the specs for sure.

Axle i.d. measures 17.1mm, the bolts o.d. measure about 17.8mm (yeah, they are way too tight)

And a source for bolts?

The crank had the self extractor rings with aluminum bolts that threaded into an aluminum axle. No sign that anti-seize compound was used.

aluminum bolt threads flattened. Fit is extremely tight in axle.

Threads in axle look okay

left side (on the right) bolt sheared off shoulder.
