Stainless Steel self locking nuts, some of the widely known designs are Aerotight, Nylock, Staytight and Philidas.
Full Stainless Steel nut with an undersized nylon insert that when fastened get deformed but not cut by the mating thread that creates a lock that will also dampen the vibrations between the thread and the nut, this also provides a moisture and gas seal. As the nylon insert gets deformed not cut by the mating thread it can be re-used a limited number of times.
Unlike the all-metal locking nuts the nylon locking nut can be affected by high temperatures so please consider one of our other all metal locking nuts if this could be the case.
