Arbiter Posted November 12, 2009 Share Posted November 12, 2009 Hi Folks, I have been reading a number of books on aircraft design and construction and all of them say use only aircraft quality hardware. This would seem straightforward, but I am confused. The confusion lies in which specs are the correct to use. Bolts for example are usually called out as AN-something. However, this spec is now supplanted by NASM, but people don't call them NASM-Something, but AN still... Does anyone else find this confusing? Also, I have seen some information that say Milspec is the same as AN... Can anyone provide clarity to this confusion? The reason I ask is because I have hardware libraries that have milspec bolts listed that I can use in modeling and they appear to be similar to AN bolts. I don't want to use the wrong spec bolts, so I was hoping someone could add a little clarity to this issue. Thank you very much in advance! -Chris Quote Chris Zupp ~Aircraft Designer~ Preliminary Design Sequence I: Project Endeavour Aeronautical/Mechanical Engineer Private Pilot Link to comment Share on other sites More sharing options...
