Regarding my earlier comment about the use of an anti-seize vs. a threadlocker: I don’t have a K3S, so have no direct experience with the screws being discussed; I haven’t really been following the SS screw thread, therefore didn’t realize that they apparently have the conversion coat Howie mentions; this being the case, I would agree with Howie that most OM’s shouldn’t need to take extra measures to ensure retention of the subject screws.
Having been a motorcyclist who maintains his own for 50 years, I do have considerable experience with the proper application of threadlockers, and as previously stated, it wouldn’t seem that use of one is really indicated here. FWIW, if I were subjecting electronic gear to a high vibration environment w/o taking steps to isolate it from the vibrations, I’d have greater concerns than a screw or few coming loose, hi. 73 de Dennis KD7CAC Scottsdale, AZ > On Jun 18, 2015, at 8:09 AM, Howard Hoyt <hh...@mebtel.net> wrote: > > Properly done, hot-process black oxide finish on plain steel with a wax > sealer can be quite corrosion resistance, there is even a MIL spec for that > (well, there is for everything including waffles, I suspect!).
