Quarter Scale ServoBlocks with tubing

Our clamping hubs offer a cheap way to attach hub mount gears or wheels to a shaft. Clamping hubs offer several advantages over set screw hubs. First, they do not damage the shaft which they are attached. Second, they offer more holding power in high torque applications. The disadvantage is that they are not as equally balanced for high speed use. The side clamping machine screw is 6-32 and accepts a 7/64” hex key. These clamping hubs work with our ServoBlocks.
