I think you mean SAE and ??WHY??, when AN is sufficient? See you in Mt. Vernon - 2006 - KR Gathering
See N64KR at http://KRBuilder.org - Then click on the pics There is a time for building and a time for FLYING and the time for building has expired. Daniel R. Heath - Columbia, SC -------Original Message------- Ok.....I've done my homework and I understand the difference between ASE graded hardware and AN standard hardware. Has anyone here used titanium bolts in thier airframe? Other than FAA examiner scrutiny (such as with the WAF) is there any reason not to use them besides price?
