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.

Good stop nut, but not for engine side of the firewall.
How do you review a bolt? I trust Aircraft Spruce to do their due diligence sourcing their hardware so as not to be selling counterfeit parts.
Parts I ordered and previous parts arrived and were exactly what I ordered and function perfectly- I needed a new Vacuum pump for my Cessna150 and is working perfectly. Thx
Great , exactly what I wanted and shipped the way I asked
It is hard to get excited over stop nuts but they appear to come in bags of 25. This is not mentioned as best I can see. I think this should be stated as when making an order up for stock, whether is is 20, 25 or 30 does not matter much. I much appreciate that one can purchase the nuts one at a time, but knowing that they can come in bags of 25 each has merit.
Best nuts ever.
just as described
I always count on Aircraft Spruce!
For the certified version, the plastic will be either green, red, yellow, or purple. The different colors denote the different approved manufacturers. For the commercial grade stop nuts, which have not been tested to the MIL spec, the plastic will be white.
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.
