youve probably already realised it by now, but just to confirm that crank bolts do not hold on cranks in a square taper setup.
They are used to force the the cranks onto a tapered widening spindle, which stretches the area surrounding the crankhole.
This is well within its elastic limit, so the crank clamps hard onto the spindle gripping and stopping it sliding off.
After installing your crank arms, its actually pretty safe to remove the crank bolts and ride without them.
