An adjustable steering column assembly which includes an adjustable shroud that supports a steering column shaft, a support bracket that is fixed in position in the vehicle, and a clamp mechanism that selectively secures the shroud to the support bracket, the clamp mechanism comprising a fixed rack that is secured to the shroud or the bracket, and a moving rack that is movable towards and away from the fixed rack during operation of the clamp mechanism, in which the fixed rack comprises a support portion and at least one row of teeth which are carried by the support portion arranged spaced apart from one another, and the moving rack comprises a support portion and at least one row of teeth which are carried by the support portion. One or both of the support portion and teeth of the fixed rack are resiliently flexible so that in the event of moving from the first to the second position where a tooth-on-tooth situation arises the teeth of the moving block displace the teeth of the fixed block in the direction of movement of the moving rack so that the teeth of the moving rack can occupy the region that would otherwise be occupied by the teeth of the fixed rack teeth.
