The spline nut can be attached to the housing via the flange, making assembly simple.
It is optimal for locations where the housing may be deformed if a keyway is machined on its surface, and where the housing width is small.
Since it allows a dowel pin to be driven into the flange, angular backlash occurring in the fitting can completely be eliminated
