SparkFun's Description of the Clamping Hub - 4mm Bore
These clamping hubs are a great and cost-effective choice when attaching hub mount gears or wheels to shafts or tubes and can be a better option than set screw hubs if you don’t want to risk damaging whatever you need clamped. These clamping hubs have a 4mm bore, four 6-32 tapped holes, one 6-32 machine screw for tightening, and utilizes the 0.77" hub pattern.
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.
