QD NUT FOR REAR WHEEL
QD nut for the quickly-detachable rear wheel setup, also listed as W1052.
This is the QD nut, part number 37-1052, used on the quickly-detachable rear wheel setup. The catalog also lists it under the earlier W1052 number, so if your parts book still shows that designation, it's the same piece.

It shows up specifically in the Quickly Detachable Rear Wheel figures, including the version marked not for U.S.A. spec, which tells you this nut is tied to the QD wheel hardware rather than a standard fixed rear wheel arrangement. Its job is to secure the rear wheel assembly on bikes fitted with the QD system so the wheel can be pulled without disturbing the chain and brake.
We've got this listed across a long run of catalog years, so it's a part that stuck around largely unchanged through the QD wheel's production life. If you're not sure whether your machine has the QD rear wheel or the standard fixed type, check your hub before ordering.
