The M4x8.8 mm flat washer is a tiny thing, but it has so many uses that today's mobility scooters and power chairs would soon break down without it. Well, maybe that's a little exaggeration, but this 4 mm hole size (close to 3/16") by 8.8 mm (about 3/8") outside diameter zinc plated flat washer is used on a myriad of Pride Mobility and other brands of mobility scooters.

You can find this washer used on Dart shroud assemblies, Go-Go Elite Traveller battery box handles, as well as on numerous scooter controllers, frame parts, and so much more. Just about anywhere your Pride Mobility scooter uses a very small 4 mm screw, it is probably backed up by this humble little flat washer.
