Abstract
A screw and nut assembly for adjustably positioning a headlamp unit relative to a support plate so as to realize proper optical aim for the headlamp unit. The assembly includes a one-piece plastic nut member having a shank insertable into a mounting hole formed in the support plate. The shank has one end formed with a base section and has the other end provided with a pair of spring arms which extend rearwardly along diverging axes towards the base section. The free end of each spring arm terminates with a plurality of teeth so that after the shank is inserted into the mounting hole in the support plate the spring arms move laterally outwardly to cause the teeth on each arm to engage the outer surface of the support plate and thereby hold the nut member in place.
