Mythbusters: Chemical thread locking (adhesives) works as a lubricant during tightening

The Myth: Chemical thread locking (adhesives) works as a lubricant during tightening.

The Truth: Chemical thread locking is a traditional solution used to protect bolted assemblies against self-loosening. The majority of users of this solution consider chemical thread locking as a lubricant. This approach is not usually realistic. Since the lubricant effect of this adhesive depends on the cleanliness of threaded surfaces (surface energy + roughness), materials, chemical properties of adhesive (polymerisation speed), temperature, tightening speed and its sequences (in the case of multi-joint assemblies). For the many applications, chemical thread locking reduces friction but this does not have the same effect as a real lubricant. For this reason, friction values are not mentioned on chemical thread locking packages.
