Wheel is a circle with multiple layers of steel rims. The outler layer extends to all six sides while the inner layer is just circular.
This Wheel icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,000 icons, all in the same style and quality.
