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

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.
