Another reason to invest in a torque wrench and appropriate adapters, here an allen wrench to socket. My first experience with
this was with an FSA crank in 2005, sans torque wrench. First ride L crank loosened up, bolt disappeared somewhere in the
first 8 miles of the ride. Had to one leg it back to the car. IME it would be REALLY HARD to cross thread the oversized crank
fixing bolt. Stripping same would require a lot more torque than FSA suggests. Loktite should have worked also. And of course
neither the bolt or the axle are aluminum. The crank is and the hazard there is mis-fitting the splines and slicing off the splines
while tightening up the bolt.
