Loose/wobbly screen hinge

So I've got X1 Nano Gen 1 with quite a good deal. After quick inspection I've diagnosed that screen is rather loose in such a way even when the laptop cover is closed I could 'wobble' the cover couple of degrees and hinge did not give any tension during this interaction.
I've disassembled those hinges from the top and the bottom cover. The hinge alone (both left and right) could be easily separated into 'screen-driver' and 'base-mounted-to-bottom-cover' (sorry but don't really know the nomenclature).

Photo 2 - 'base-mounted-to-bottom-cover'

Photo 3 - 'screen-drive' nibble goes into hole in 'base-mounted-to-bottom-cover'

Probably obvious but wanted to be clear. Even without screen cover leverage the hinge is wobbly and move couple of degrees.
And here is a question or two. Is there a way that I could fix it that bolt is not so loose in that bottom piece hole or should really go for some sketchy hinge replacement?
