Abstract:
A coupler nut with multiple bore diameters that are symmetrically stepped in both directions away from the center bore diameter. The bore diameter at the center is the smallest, and each pair of steps away from the center bore increases the bore diameter. This means that the coupler nut has no single, correct vertical orientation. It has no top or bottom, and as such is vertically ambidextrous.
