[HWYSTR455]

A loose balancer bolt can taper the crank snout, but can't see how it would damage the threads.

There is a run-out value for the crank snout, and used to check that when buying used OE cranks. But it's been a while since I've used an OE crank.

Remove the bolt, inspect the threads, and chase the threads in the snout. That should remove any doubt of damage. If the threads look fine when you remove the bolt, you're probably OK.

As others have commented, make sure the correct thick washer is being used on the bolt. If there's any question, replace both the bolt and washer. The ARP replacement ones are fine, and I've used them exclusively for years.
