[Elecraft] Loctite

[Harry Yingst via Elecraft]

On this subject I would tend to believe some of it's due to thermal expansion and contraction

A small drop of Loctite® 222, which is purple in color, would be appropriate for these small screws in this application. However, I don’t consider most cars to be a high vibration environment. If one were to regularly drive on cobblestone or washboard surfaces, then a thread locker might be warranted, but that would be more of a low frequency vibration, very unlike a high frequency vibration, such as might be generated by a high RPM 4 cylinder motorcycle engine.

Even though the screws may be of a stainless steel material, there is still a slight potential for galvanic corrosion. I’d think that use of a heavy bodied anti-seize compound on these screws would be all the “thread locker” most OM’s would need.
