Yea, that’s going to happen. A loose square taper crank is basically a ruined crank. Do yourself a favor and use a torque wrench to make sure the bolt won’t come loose (35 to 45 ft-lb). Also replace your crank bolts with ones that use an 8mm allen wrench to tighten. At least then you can carry the right tool to get you home. You’ll probably still have to replace the arm but at least you can finish your ride.
