Shaft Coupler - 1/4" to 1/4"
These stainless steel shaft couplers allow you to couple two size shafts together. They can be used for connecting motor shafts to drive shafts, or two different-sized shafts. These shaft couplers have a length of 0.75”, a outer diameter of 0.42”, and couple 1/4” to 1/4” shafts.
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.

shaft couple
good finish, smooth bore, finished edges. High priced!
Tolerances on the coupler seem good enough. However, on the set screws, a 3/32 hex key is too big and a 5/64 is too small....anyone else have a similar experience?
Prepare to lose these set-screws. I was setting something up on an optical table (a large metal table with regularly spaced screw holes that allow you to bolt things to the table), and one of these set screws fell down a hole, never to be seen again. It would be nice if Sparkfun provided the size of the screws so that you could go order more, or better yet, they could provide a spare screw with the shaft coupler.
These require a 3/32" hex key.
