The amount of specialized AN hardware and fittings never ceases to blow my mind and excite me but I find it is very hard to locate some if this stuff. Is there some kind of a reference book for this or do you just flip through you aircraft spruce catalog to find what you are looking for?

I just search for and download the actual spec sheets online. There is the "standard aircraft handbook" that shows the more common stuff.

Actual AN reference books are very thick and expensive, and for the most part kinda useless. Once you understand the numbering system for determining bolt sizes, you don't really need them. Contact MSC and see if they still have their catalogs available. They are a monster book several inches thick and they have all kinds of charts on different types of hardware and tooling and just about anything you can think of. They are free. If they don't offer them anymore, then they do have an online version. https://www.mscdirect.com/webapp/wcs/stores/servlet/customer-service/information

I have an older copy that I keep and I wouldn't take anything for it. You have to see it to appreciate it. I would recommend that any builder try to get a copy of it.

Beyond that, here are a couple of books available at Amazon or your local book store that are pretty informative.

About $20 each and both are pretty good. Here is an actual reference book, 1 of a set of 3 Altogether they are about 4 3/4" thick. No idea what they cost these days. Note, I am going to post another thread on HBA that has references that should be helpful to other builders. They can pick and choose what they want to print out or save on their computer.

I get the convention for fasteners bur AN tube fittings and all of the specialized weird fittings that you don't know exist is kind of more what I am after. I was kind of hoping for a poster to post in our EAA hangar that has the common hardware and tube fittings. 6.

It's like$30 bucks for 5 large posters. They will be right on the home page.

NAVAIR 01-1A-8 Structural Hardware Manual for fasteners, and -20 for hydraulics. Not everything, but most of what actually matters, in detail.

Anyone have an opinion on Genuine Aircraft Hardware? They have a reference book. I don't know what's in it. I'm not sure it's the same as the catalog, which apparently they make available to libraries for free. They also have info like this:
http://www.gen-aircraft-hardware.com/template.asp
http://www.gen-aircraft-hardware.com/template.asp?pagename=ftgs
However, I haven't figured out where the index for this type of page is.

I found this:
http://aircrafthardwarecatalog.com/images/ECAS_Catalog_Final.pdf
If it doesn't download correctly, you may have to go to aircrafthardwarecatalog.com and click on the appropriate button. I had to.

Dana's link to everyspec seems to have the actual standards in it, which may be useful for design purposes.

The problem with having access to many specs is that a builder often doesn't know the proper term to use when searching for an item. This can lead to a lot of time spent just trying to locate something, especially if there is something you don't know exists. With bolts and nuts its fairly easy to come up with a spec for a common hex head because you just use a basic series of alpha-numeric figures. If you want a longer bolt, the -3 (3x 1/16) becomes -4 (4x 1/16) etc. The real work goes into finding a vendor who has that specific length. When it comes to fittings, that is where knowing the correct name of the item you desire becomes more difficult. There are also less expensive industrial versions of many fittings that work just as well as the AN spec items. Having a quick reference chart on the wall will show you things that might be adaptable to your situation and the differences are readily apparent. Most people prefer to take a quick look at a chart rather than research endlessly on line. I have a set of the charts from "Discount Hydraulic Hose"
and I can tell you first hand that they are very good. I think they are 24x36. I misquoted the price, they appear to be \$18.75 now. Besides that, they just look neat hanging on the wall.

Also go to Earl's or Russell and order a catalog that shows you a lot of what is available and how to assemble it.

I have never encounter a really good comprehensive one, even the OEM internal ones.

The second half of AC43.13-1b chapter 7 has a basic one.

Aircraft spruce tends to use the AN specs which are fine but the NAS / MS ones can be a bit lighter weight wise.

There is this one of washer
