ABSTRACT:
A novel, self-sealing a headlamp adjustor mechanism is used to effect pivotal movement of a movable headlamp component in a headlamp arrangement. The headlamp adjustor mechanism includes a bushing having an initially unthreaded bore therethrough and an adjusting screw member having a shank. The shank of the adjusting screw member has a threaded portion and an unthreaded portion. When the adjusting screw member is rotated through the bore, female threads are cold-formed within the bore as the threaded portion contacts the bore and the cold-formed, female threads are deformed and collapsed against the unthreaded portion to seal the bushing against the unthreaded portion as the unthreaded portion contacts the cold-formed threads in the bore.
