Jerry ,

Oops, sorry to get your name wrong. I suppose that wasn't nice, but after you posted so much wrong information on fasteners, I suppose you could allow me to be wrong about your name?

I addressed your comments about grade5 bolts. If you want to talk about aircraft safety wire, I can address that too. And likely with much more actual knowledge than yourself (not just some BS I heard somewhere).

However, to continue the fastener discussion, you point out the brochure describes that aircraft-quality fasteners are used on the Kcars. Well, to that point, grade5 bolts are used on aircraft in those areas where the requirements are such that a grade5 bolt is a proper selection. It is not correct for you to assume that aircraft-quality means AN series fasteners (or MS fasteners for that matter). I have been an Aerospace Engineer for many years and have worked on many space launch vehicles, target vehicles, interceptors, etc... and I can tell you that the term aircraft-quality by itself means simply that the specifications of the fastener are controlled and verifiable and that the specific fastener selection meets the requirements based on an Engineering evaluation.

Again, I ask (this time more specifically): Where are your calculations or test results that show grade5 fasteners in any of the applications you are complaining about do not have sufficient margin for acceptability?

If you do not have any such calculation or test data, why would you purport to be an expert? BTW, having bolted a few cars together does not make you an expert. If any of my Engineers came to me and told me their bolt selection was made based on anything other than sound Engineering, I'd fire them. Seat of the pants doesn't cut it...
