Anaerobic Threadlockers form a hard lock and are applied to a fastener then installed into the mating part. In the absence of air and the presence of metal, a chemical reaction takes places which causes the material to harden, unitizing the assembly. Vibra-Tite VC threadlockers are soft locking materials which are applied to a fastener and then air dried. Once assembled, the vibration absorbing characteristics keep the fastener isolated and prevent loosening. VC threadlocker can be easily adjusted, removed, and reused.
