Rumors: Chemical thread lockers (adhesives) can be used as lubricants when tightening bolts

Chemical thread locker (adhesive) can be used as a lubricant

Fact: Chemical thread lockers are a traditional solution to prevent the bolt assembly from loosening itself, and most users of this solution use chemical thread lockers as lubricants. This action is often counterproductive, because the lubrication effect of this adhesive depends on many factors, such as the cleanliness of the thread surface (surface energy + roughness), material, chemical properties of the adhesive (polymerization rate), temperature, tightening Speed ​​and sequence (such as multi-connector components). In many applications, chemical thread lockers reduce friction but do not achieve the same effect as real lubricants. Because of this, there is no mention of the coefficient of friction on the packaging of chemical thread lockers.
