alloy bolts snapping in half when tightened
Bolts are not threads in a chainring. They usually fail from the combination of shear and tension at the conjunction of the thread and shank while being tightened. Chainring bolts are particularly vulnerable because they necessarily have a hole through the middle nearly as big as the root diameter of the thread.
It's clearly possible successfully to use 7075T6 chainring bolts, either with nuts or screwed directly into the chainring or the crank, but if anything is going to fail first it's most likely the bolt. This is in some ways a good thing, because it's the cheapest part to replace.

I've had a few alloy bolts snapping in half when tightened at the recommended torque. Annoying
