I would first run a tap through there, I think its 1/4-20 but don't quote me on it, and see if that cleans it out. -
ok let me see if I can understand whats happening here
a small piece of metal is sitting in the threads a loose piece?
^^ is this correct?
OR
A burr or shard is protruding outwards from the threads and is not loose a loose but instead "built in"?

Im thinking any of the below could be possible solutions
quick blast of compressed air
precision pick set
thread restorer
tap- use some sort of cutting oil
