Is this a thing for screws?
@Tathar yes, a sort of glue for high-vibration environments
i'm a little surprised how many people don't know what it is! if you've ever been taking something apart and saw a blue or red streak on the head of a screw, that's probably residue from thread-locking fluid (i think an intentional mark to indicate "yes we remembered to put the thread lock on this bolt")

I don't remember one being on the head, but I know bolted joints can have some blue stuff (wouldn't really call it a fluid) on the bolt thread. I knew it had to do with keeping mechanical stresses on the bolt low enough to prevent the shaft from snapping, because it couldn't shift around in the nut.
@Tathar yeah that's thread-locking fluid
it's not fluid after it cures, but it's about the viscosity of water when you apply it to the bolt

@Tathar I'm not sure what you mean "don't have to apply it at the time of assembly" because that sounds like it was applied at the time of assembly to me if it was applied at the factory?

I assembled the chair, but the blue stuff was already on the bolts and hardened when I got the unassembled chair.
@Tathar oh! huh, that'd be a different sort of formula then probably? could be something pressure-activated or something

@Felthry
Yeah, this stuff was already on there and hardened though.
