It varies - I tend to use whatever is supplied. With plain nuts I would
always use the Loctite. With Nyloc nuts I would only add the Loctite if
the hardware was showing any sign of galling.
>Can u even use loctite with SS nylock nuts ?
It doesn't seem to be a problem. I try to avoid applying Loctite where
the nylon ring would be, but I wouldn't think it would be a disaster
either - whatever, that nut is *locked*.

There isn't any need to use the weaker grade, as Blue grades are
specifically designed for disassembly using hand tools, for the typical
range of thread sizes used in antenna work and other light-to-medium
Purple is mainly intended for tiny instrument screws where there is a
risk of the screw snapping.
>What I would not recommend is red loctite. Red loctite is as good as

Agreed. Green Loctite will give you a hard time as well.
Those high-strength grades of Loctite can be useful when using
all-thread studs, where you want to lock one end permanently into place.
You can then use the Blue Loctite on the free end of the stud.
