My left (non-drive side) crank arm loosened up on my last ride. I put the wrench on it and tightened it up but realized I didn't know how tight it should be. Since it's the left side, it seems it could loosen on it's own, but then again I wouldn't want to strip the bb or threads.
This is a Shimano RX100 crank with 105 bb.
