Abstract

To align an aperture (16) in a nut (12) with a hole (18) in a threaded stud (14), the nut (12) is rotated on the stud (14) to move the aperture (16) over the hole (18). Light is projected into the aperture (16) as the aperture (16) approaches the hole (18). The light is sensed when it projects from the aperture (16) through the hole (18) upon movement of the aperture (16) into alignment with the hole (18). Rotation of the nut (12) is stopped in response to sensing of the light.
