Your statement is not incorrect, but these aren’t ‘bolts’, they are fasteners, there to keep a panel on, not holding the wing together. It’s the kind of thing you write up and let maintenance fix at the next stop. Inspection panel fasteners wiggle loose. Not a big deal in small numbers. I have reported such on many aircraft and still flown.
You would think a wing skin fastener would be be torqued in with blue thread lock or something.
