Loose SCREW ON 240Sx s14

[jesusgonzalez7]

Hi, I recently bought a white 240sx, and i noticed it has a loose screw, I took it out because it wasn’t screwed to anything.

I think it has some kind of relation with the drive bands,

Here’s a picture, the red arrow points where the screw was.

Could you please tell me whas the function of this screw?What parts are apparently missing?AndI there any risk to drive it as it is?

Thanks for you’re help.
