Cad stop nuts are furnished to military specifications. Stainless is furnished to military specification and commercial grade.

Q: What is the color of the plastic in the AN365 elastic stop nuts?

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.

Q: What is the thickness of the AN365-624? This is for bolt length planning for propeller installation.

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".

Q: Is this the same nut as a MS20365-720C?

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.

Q: I would like to know the difference between: AN365C-1032 and AN365-1032C

The A nuts will be cad plated steel.
