And so it's okay for the threads to make contact, and presumably get ground down, with the CR parts? Or doesn't the grinding happen? (I'm used to working on cars, so metal on metal isn't always a good idea).
No grinding should happen chainrings are prevented from riding on the threads cuz they're resting on the shoulders of the crank arms. If you bash something with the bash guard it may contact threads of bolts but you don't use that area of threads anyway so no biggie.
Also if you get steel bolts they'll be harder than chainrings or bashguards
