These are Military specification versions of what is commonly referred to as a "Nylock" or nylon locking nut. They are rated at 125,000 psi tensile strength and for operating temperatures of up to 250° F. The AN364 series is a half-height variation for bolts loaded primarily in shear. The AN364 specification is equivalent to the MS20364 and newer MS21083 specification.

Reusing Nylon Locking Nuts
The FAA has issued guidelines on the reuse of nylon locking nuts. Specific recommendations have been published for larger sizes (7/16-20 and up), but the general rule is that you should not be able to turn the nut by hand once the locking insert engages the male threads. If you can turn the nut with your fingers, it must be replaced. When in doubt, replace!
