The m4 flange nuts on the wheel axle are flat to avoid hurting the line in case it is attached on them.
The m4 flange nuts on the front wheel are serrated to lock better on the side plates.
Take care not to over-tighten the m4 nuts to avoid damage on the threads. Especially the flat ones when the dyneema line is installed between them and the side plate.
