The screw is a little hakelig, especially since you have very little space in the pedals with the wrench. For the reflectors but also tight. Before breaking off they are not prepared, however. Finally, end the thread in the plastic. Hint: It is this plastic warps fast, so when tightening please feel. Otherwise you the plastic pulls out with. If available: Fix the nut on the thread with a little thread adhesive, better safe than sorry ;-)
