Set Screw Hub - 1/4" Bore

Set screw hubs offer a cheap way to attach hub mount gears or wheels to a shaft. The hub offers 4 equally spaced 6-32 tapped holes utilizing the 0.77" hub pattern and is precision machined from 6061 T6 aluminum. The set-screw is 10-32 and uses a 3/32” hex key. This hub has a 1/4" bore.

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.

    Hi, I have a Stepper motor with a 5mm shaft (sorry, I'm using the metric system), which one of these hubs would I need? Iv tried converting 1/4, 3/16, 5/16 to mm but I can't get 5mm.

Nice item

It worked beautifully. I am satisfied, it is exactly as described

Nice Part, Way too expensive

This thing is not worth the cost, unless you really want/need it. I was in a hurry or I would have made something else to use. This works as it should, and is a good part.
