Genuine Buddy & Blur OEM External Tooth Lock Washer #6

External Tooth Lock Washer Suited to Genuine Buddy and Blur Models

This external tooth lock washer is an OEM-style replacement made for several models in the Genuine Buddy and Blur range. Made from zinc-plated steel, it has 12 serrated teeth that bite into the mating surface and help keep fasteners from working loose under vibration. It is one of the Genuine Buddy scooter parts used to hold steady in key areas such as the handlebars, headset, and bodywork.

Build and Layout

The washer is zinc-plated steel, which gives it a corrosion-resistant finish that holds up well in mechanical use. The external teeth sit along the outer edge and grip the surface they contact, giving firmer hold and stability where vibration is a concern.

Why a Close Fit Matters

This part is built to OEM specifications, so it lines up with the original assembly. Its measurements allow it to take the place of the factory component, supporting consistent performance and reducing the chance of loosening over time.
