AN364-820A Self-Locking Nut

(9 customer reviews)

AN364-820A self-locking nuts are required to keep your tailwheel fork attached to the airplane. It is acceptable to reuse these ny-locker nuts until you are able to turn the nut with your fingers through the nylon locking material. When you can do that, it’s time to get a new one.

AN364-820A specs:

  • 1/2″ – 20 thread size
  • Cadmium plated
  • Precision made
  • approximately half the height of a regular AN365 nut

Note: The AN364 (thin) stop nut is for use in structural applications where the bolt is loaded primarily in shear or in any application where the tensile strength of the regular height AN365 is not required.

    Quick shipping , when the part turned up ordered wrong, Flyboys sent the new control arm with full credit on the wrong part…..super!

    I bought a tail wheel assembly and steering arm from Flyboys a few years ago, both have worked great. Recently though I was having a problem with my tail wheel coming out of the locked position way too easily. Flyboys fixed me up with a new locking pin and everything is as good as new. They are very helpful, knowledgeable, enjoyable to work with.
