One tip is to replace the existing screws with nylon ones, if you can find any (they're readily available from Farnell, for instance). Do them up fairly tightly, but not so tight that they shear off, and they'll stay that way more or less permanently. The stretching of the nylon acts as a thread-lock device. Of course, if they DO come out, nylon is non-conductive...


Speaking out of experience from racing r/c cars for many years, i'd recommend using blue locktite, red locktite if you never mean for the screws to come out again. Red locktite has to be heated to unlock.

Personally i've blue locktited my primary Empeg because that the one that goes in the car.
