Fastener standards documents

Where would one find PDF files with the following standards:

AN (Army/Navy),
MS (Military Specification,
NAS National Aerospace Standards

A google search uncovers mostly suppliers of AN/MS/NAS hardware...I
want the defining documents.

Thanks,

ANSI, ISO, SAE etc. They are not free.

I just found this:

At least some can be found at http://assist.daps.dla.mil/online/start/
IIRC. Don't know if all are PDF files.
"All ASSIST documents are now available to users free of charge!"

OOPS ....sorry for the OT post !!!

 

Another free place is at

IIRC such are so noted.
In addition, sometimes an older standard actually is required.

 

This is the first place I start! All Gov't specs (Mil, AN, MS) are free,
and if they've been superseded......

You need to be really be carefully here because I believe most if not

Didn't know that. It just seems that most vendors are still using the
designations that have been cancelled. For example, I searched for
MS20426 rivets and you find tons of suppliers that use this
designation rather than that which superceeded it. I guess these
numbers have become terms of trade in some way?

I don't believe SAE gives any prints or specifications

And that's probably one of the reasons the old part numbers will never
go away. If you want to convince folks to migrate to a new standard
you have to make it so easy and painless that it would be unthinkable
to do anything else. For just about everything I do any supplier or
fabricator I deal with is perfectly at home with the old part
numbers. They know what I am talking about and they can buy the
components just fine from any number of suppliers who use the same
specs.

Maybe I am wrong, but if SAE went throught the trouble of making the
specs available at no cost, and maybe even good solid models, adoption
would probably not be an issue. Otherwise, adoption of the new
designations will only happen due to being forced to do so due to the
nature of the work being done and just about no other reason.

I sort of fail to see why Mil specs would go to the SAE.
Low bidder?
