To Scuffers : yes,
To redhanded : not sure : if the bolt fits tigh, and has only one axis of motion I am not sure the HUMS could detect the movement of the bolt. More than that, if flight, under high lift, I hardly suspect the bolt from moving.

Years ago, flying Lynx, I encontered unusual vibrations in flight while collective down only. It turns out to be a missing part in the collective control chain, but under lift, there was no vibs.
