Pololu recommend M3 screws that are at least 22 mm long, such as Pololu's [25 mm M3 screws](https://core-electronics.com.au/machine-screw-m3-25mm-length-phillips-25-pack.html). These scooter wheels (also called inline skate wheels) are designed to work with standard 608 bearings and are compatible with Pololu's [Aluminum Scooter Wheel Adapters](https://core-electronics.com.au/search/?q=aluminium+scooter+wheel). The adapters make it easy to connect these wheels directly to an assortment of motors for use in robot drive systems. The picture below shows an example of the [70 mm scooter/skate wheel](https://core-electronics.com.au/scooter-skate-wheel-70-25mm-black.html) mounted to a [25D gearmotor](https://core-electronics.com.au/components/motors/metal-gearmotors/25d-mm.html) using a [4 mm scooter wheel adapter](https://core-electronics.com.au/pololu-aluminum-scooter-wheel-adapter-for-4mm-shaft.html): | [![](https://core-electronics.com.au/attachments/localcontent/0J6901_24038c3642c.jpg)](https://core-electronics.com.au/attachments/localcontent/0J6901_26057e0109f.jpg) | |---| The tire portion of the wheel is made from polyurethane, which offers plenty of traction, and the rim of the wheel that contacts the ground is narrow to allow it to easily turn in place. These make great wheels for medium-sized robots. For smaller robots, consider Pololu's [Pololu Wheels and Tracks](https://core-electronics.com.au/hardware/wheels.html).
