Any screw can come loose at any time. Sooo, whenever I put together any screw or bolt that I do not expect to take apart routinely, I use Loctite or fingernail polish to 'lock' it in place. When I built the K3 (#4515), I used that on a few screws/nuts, specifically, the handle, the feet, the support bail and the ANT1 and ANT2 hold down screws/nuts. I wouldn't go out of my way to use the stuff, but if you have any problem, just use that.
Best way is to put a drop on the threads INSIDE the nut and then attach it and tighten it, then place a drop on the exposed screw/bolt threads. If you are concerned about electrical connection, then only place it on the exposed screw/bolt threads after tightening it. For the handle, feet and bail, electrical connectivity are not a concern and you will never expect to need to remove these items. IF you DO need to remove them, they can be removed with only a moderate amount of extra effort and it does NOT destroy the threads. To be thorough, there are two different types of Loctite. The usual is designed as described above and is essentially fingernail polish. The other type is a much stronger type for where a near permenant bond is required. This may destroy the nut/bolt if removed, altho some (epoxy) types are designed to be removeable after heating to 400 degrees.
