Abstract: The invention relates to a screw which can be screwed into a component and which will resist further screwing into an internal thread within said component once a maximum torque has been reached. For this purpose, a screw body having an external thread is combined with a screw drive element which projects into a bore within said screw body and, within said bore, is connected to the screw body via static friction. At least part of this combination is made of a plastic material, with the static friction having the effect of a slipping clutch when a maximum torque acts on the screw drive element. The screw drive element is connected to the screw body via a ratchet in such a way that when the screw body is unscrewed from the internal thread within said component, turning said screw drive element will cause the ratchet to engage, thereby entraining the screw body.

Abstract: A position control apparatus for a raked steering column including a stationary bracket having a pair of vertical legs on opposite sides of the steering column, a spacer on the steering column between the legs of the stationary bracket, and a clamp on the steering column for squeezing the legs of the stationary bracket against the spacer. The clamp includes a long bolt spanning the legs of the stationary bracket, a nut on the bolt, a one-way clutch between a head of the bolt and the stationary bracket permitting rotation of the bolt in only a tension-increasing direction, and a snap-on operating lever rotatable as a unit with the nut. After assembly on a vehicle, the clamp afforded by the bolt can be adjusted without changing the terminal positions of the lever by rotating the head of the bolt in a tension increasing direction while the operating lever is maintained in a clamped terminal position corresponding to maximum bolt tension between the vertical legs of the stationary bracket.
