>My gut feeling would be that AN bolts would be the way to go, and that stainless steel fasteners should only be used for non-structural applications, such as trim attachment, etc.- - BUT I just did a quick internet search, and found a website that lists MS27039C stainless steel machine screws with 125,000 PSI listed strength:http://www.skybolt.comThe website won't allow me to give a direct link to the specific page, so you'll have to go over to the left hand side of the page, and click "online purchasing", then click on "AN-MS-NAS Screws", and then "MS27039C Screws-Stainless". A screen shot is attached for reference.So, the short answer is MAYBE you can buy AIRCRAFT GRADE stainless steel fasteners that have strength comparable to AN bolts - but you should check very carefully with the supplier regarding the strength. I have no idea how these stainless steel fasteners compare with regards to fatigue strength, or anything else, for that matter.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/skybolt_114.jpgle, List Admin.________________________________________________________________________________Date: Fri, 18 Dec 2009 06:38:28 -0800 (PST)
