These precision-made nuts are reliable and economical fastening devices The fiber insert gives a friction grip on the threads of the bolt and holds securely. 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. Cad stop nuts are furnished to military specifications. Stainless is furnished to military specification and commercial grade.

I intend to use these in a Live Steam hobby project. I intend to use them to join one inch high Steel rail sections together.
Always a pleasure to see the folks in West Chicago. They are so helpful and greet everyone with a smile. Thank you for coming to the Midwest. I look forward to the time when you start carrying wood, as I am restoring a 1942 Stinson L-5 Sentinel and a 1945 Percival Proctor - both ground up restorations. Thanks for your assistance.
They lock! True AN hardware to Mil Spec.
Exact size ordered, work perfectly.
These things are the way to go for very secure connections
I write reviews as a hobby. However, its kind of hard to attach a Product Review to a lock-nut. Nevertheless, AircraftSpruce requested my assessment. These appear to be very well-made. While I do not know the country origin of manufacture, Im hoping these are NOT made in China. I think it would be in the best interest of AircraftSpruce to list Made in America whenever it applies. On the admin side, AircraftSpruce efficiently managed my multiple orders. The real test will come over time, both functionally and weather or not AircraftSpruce carpet-bombs me with ads.

AN365-624A thickness/height is .453".
The data sheet I have has the height at .236" +/-.016", and thickness/flat surface across flat surface, is .375".
MS20365-720C is a 7/16-20 all metal stop nut. We offer AN363-720 and NAS1291X7 that are all metal, 7/16-20 all metal stop nuts. Either should work for an MS20365-720C unit.
AN365-820A is MS21044N8.
These are both the same as the "C" represents that they are stainless steel.
The C designates stainless steel. The A will be cad plated steel.
The A nuts will be cad plated steel.
AN5 bolts use AN365-524 locknuts and AN960516 flat washers.
