X-Rail Nut (4 pack)

X-Rail Nuts allow you to integrate Actobotics X-Rail extrusion with other components of the Actobotics building system.  The X-Rail Nuts are able to slide anywhere along X-Rail and provide a threaded hole to fasten a component to.  The top of the nut is designed to sit just below the top surface of the X-Rail which creates tension between the X-Rail and the mating component for a solid connection.
