I bought a SunRace bottom bracket (BBS18). It didn't come with crank bolts, but since all the other crank bolts and bottom bracket I've used have been compatible with each other, including with other new cartridge-style bottom brackets, I expected that this would be compatible with the bolts I already have.
The crank bolts I do have went in a few turns, then the threads bound. I can force it, but this will start to damage the threads. They clearly have a different thread specification.
What different specifications exist? (And what bolts should I look for in this particular case? It's a M8 x P1.0 thread; how are these bolts likely to be described by cycle component retailers?)
