AN364-820A Self-Locking Nut

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.
