I have the square aluminium knuckles and had the same problem. the only cure is loctide. but make sure you dont put too much or you will risk gluing the whole assemble to gether. use tamiya thread lock as it is tacky to start with you will instantly know if you got it in the wrong place.
But dont take it for granted and check to see if it is secure before your races.
