I've been balancing props for almost 20 years.
I never heard of a instance of losing spinner screws in flight.

It is unusual, not normal. I'd be surprised a simple dynamic prop

Unfortunately Fly, you are right.

Guy came out to balance the prop and when they pulled the spinner off,
found that the bulkhead behind the spinner needs to be replaced.

Then the prop can be balanced.

Almost afraid to ask how much this will be....
