We’ll made stop nut that was perfect for my double shear application on rear engine dragster safety harness connections.

The nuts arrived well packaged in a small sack, a nut sack if you will. It was clear my nuts had been handled with care for shipping. I opened the package and was pleased that my nuts had not been damaged or roughed up while in transit. It is good to know my nuts were in good hands with ACS. You can trust ACS to satisfy all your nut needs.

Q: on the part manual for a cherokee it asks for part number MS20364-1032C, what is the C stand for?

C after the -1032 will indicate that this is a all-metal stop nut. You will need to go with a MS21042 series nut. MS21042-3 will be the correct cross reference part for your MS20364-1032C. You could also order part # 04-01359 which is a MS20364-1032C THIN HEX NUT.

Q: My application requires a AN364-1216A. What does the A stand for? Will the AN364-1216 work in this application?

"A" stands for non metallic insert, or elastic/nylon lock nut. They are the same part, we just drop the "a" in our system.

Q: The Piper parts manual calls for (nut) MS20365-1032C. No hits on the search. Do you have a replacement?

Use MS21044N3 or AN365-1032
