nut. Use threadlock or thin CA to keep the nut

final 2mm nut onto the screw, using threadlock or
thin CA to keep the nut from rotating.
Note: Be very careful when using thin CA as
not to glue the wheel so it won’t rotate on the
2mm x 25mm screw.
  5. Slide the wheel pant into position and
secure it using the 2mm x 8mm wood screw.
Don’t over-tighten the screw which can damage
the wheel pant.
