How do you guys keep them from working loose? I'm not even sure a little LocTite red will be enough to keep the small set screw from working loose given the beating the extension takes when doing its job. And the screw is so small that I can see it being easy to break off the small Allen Wrench trying to get it tight, or trying to loosen it should there become a need to remove it after LocTite has been applied.
