Stainless Steel Link Watch Band Pins

I’ve had a SS Link Band for some time now, and lately I’m finding the small steel pins within the clasp are starting to come out of the joints.

This then prevents the clasp closing until they’re pushed back in.

most jewelers been to don’t have the right size pins to replace, so wondering if anyone else has come across this? And whether it’s something the Genius Bar would fix? Obv outside warranty so happy to pay
