Bolt sizing

  1. Nov 20, 2008 #1
    I need to spec out some bolts according to the NAS standard. The problem is that I only have the dimensions/specifications in ANSI format. Has anyone ever worked with NAS before? I can't find anything to help me figure out what size bolt I need.

    Yes, that is exactly the data I was looking for. Thanks a million!

    I would highly recommend that if you are really spec'ing out any kind of NAS bolts that you get a hold of the actual spec, not a web site's pared down version that could be who knows how many revisions out of date. There are MANY types of fasteners covered by NAS specs.

    Well, thus far the problem has been finding the comparable to NAS fastener to an ANSI hole call out. I have the call outs, I know the thread counts, diameters, etc, that I need. The problem is I couldn't find anywhere that would tell me what they were. They only list NAS 144-158, etc. No conversion chart or anything.
