Received my spare axle bolts from Florian and confirmed the threads are M14x1.0.
I also ordered and received the M14 bolts you linked earlier and confirmed they are also M14x1.0 threads. I went ahead and drilled thru holes in them on a drill press (first with a 1/8" carbide bit, followed by a 1/4" bit, both at 450rpm). Hole size seems to match up with the Schlumpf axle bolt.
I plan on changing the cranks later this week. Will update once I’ve tried using these as pretightening bolts.
