ABSTRACT:
A motor vehicle steering column including a steering shaft, a steering hand wheel, and an attachment between the steering shaft and the steering hand wheel. The attachment includes a cone-shaped outside shoulder on the steering shaft, a cone-shaped inside shoulder in a bore in a hub of the steering hand wheel, a retaining nut on on the steering shaft, and a plurality of outside spline teeth on the steering shaft in mesh with a plurality of inside spline teeth in the bore in the hub of the steering hand wheel. Two of the inside spline teeth are merged to define a double-wide blocked tooth. One of the outside spline teeth is eliminated to define a substantially double-wide longitudinal blocked tooth groove. The blocked tooth has a lip extending beyond the ends of the inside spline teeth which seats on and slides over the ends of the outside spline teeth until the blocked tooth registers with the blocked tooth groove. The lip separates the ends of the inside and the outside spline teeth until the blocked tooth is aligned with the blocked tooth groove.
