These servo gears are made specifically to fit a Hitec C1 servo spline, allowing you to mate other gears to your servo. They have 20 teeth with a gear pitch of 32P, an outer diameter of 0.688”, and utilize the C1 Hitec servo spline.
[Actobotics](https://www.sparkfun.com/pages/Actobotics) is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.
