It is a great cross reference between the AN, MS, and NAS part numbers. Reference book pages are also viewable on the web site. The Spruce catalog is OK, but usually does not cross reference AN to MS to NAS numbers. Many of (most of?) the AN part numbers have been superseded by MS numbers, but everyone in the GA world still seems to use the AN numbers. Here's what the hardware reference book says: AN365-xxxA translates to MS21044N(xx). This is a standard cad plated steel nylock nut. The "A" suffix sometimes (maybe most of the time) gets dropped off, probably because this is the nut used in most aircraft applications. Van's drawings do not use the "A" suffix for the standard steel hardware call out. There is also a AN365-xxxC, now called a MS 21045C. This is a stainless steel version of the standard size nylock nut. Perhaps the smaller nut you saw was really a AN364-xxxA or AN364-xxxC which translates into other MS numbers. This is a low profile nylock nut (cad plated steel, or stainless). Confused yet? :-) good luck, Steve A. slowwwww build RV-6A messydeer wrote: > > Hello! > > Is there any difference between AN365-1032 and AN365-1032A? A new > number I think is MS20365-1032.

Web site: www.ecasinc.com Good catalog which I use for reference and very competitive pricing also easy to do business with. I have no interest in this company, financial or otherwise.

The "A" suffix indicates a "non-m etallic insert". According to the spec, An AN365-428 is a 1/4-28 nut "eith er all metal or with non-metallic insert". Adding an "A" after the dash nu mber forces a non-metallic insert. AN365 is marked "INACTIVE FOR NEW DESIGN AFTER 11 MARCH 1957. USE STANDARD MS20365". MS20365 has been superceded by MS21044 Specification MS21044 was cancelled 12 MAY 1999 and replaced by NASM21044. This specification does, however, retain the MS part numbering system. NASM21044 is an active speci fication. This specification offers nuts in steel, aluminum, brass, and st ainless. All flavors come with non-metallic inserts. I hope this helps.
