I would spend some time investigating, when you get them tight if they are actually tight against the chain ring, or are they tightening against themselves?
I'll have to see how things go once I get some proper lube (is WD40 ok?), but im sure the bolts arent bottoming out on themselves, cause they are threaded the whole length of the shaft. When I tighten the bolts, im sure its tight against the 'ring, cuase theres no play or slippage between the ring and crank. After they come loose, then the ring and crank start to seperate and its just the bolts themselves providing the torque, not the contact of friction between the ring and crank.
