Handle Keeps Coming Loose - Harman Mark II

Gentlemen:

What do you recommend to keep the loading door handle screw in as it keeps coming loose on my Harman Mark II? I have tightened it several times and it keeps loosening itself ???

Not to advertise but, I would try Loctite Threadlocker 272 - Red. I believe it is rated for high temp applications. It should be available at most automotive stores.

I would try a jam nut first.

You do have the nut between the handle and the door casting, right? If the bolt is over-tightened it will back the bolt out.

Hey, yes I do. I didn't realize that nut was separate from the bolt! OK, thank you so much, I will check that out and it should take care of the problem!
