b'Myth:Threadlockers dry like regular glue.Fact: Regularcraftorwoodglueisusually water-based, which is why the cure is associated with the water evaporating leaving behind a sticky layer of solids. On the other hand, Loctite threadlockers are what are referred to as anaer-obicadhesives.Thismeans theyremainstableinthe presenceofair,butwhen theyareworkedintotight gaps(suchasthegap tion protection because of the adhesion betweenbetween the threads on a nut the male and female threads that works throughoutand bolt), they are deprived the threads, and not just at the bolt head or nut.of oxygen and begin to react Mechanical fasteners are also much more expen- toformahardplastic.This sive than liquid threadlocker, and need to matchexplainswhyadropof the size of the fastener to be e\x1fective, whereas athreadlockeronaworkbenchdoesnotdry,itis bottle of threadlocker is one-size-\x1ets-all for protect- exposed to air and therefore remains stable.
