Abstract
An assembly for automatically compensating variations of the spacing between first and second structural members due to manufacturing and/or mounting tolerances. The assembly comprises a bolt, a nut and a compensation sleeve. The compensation sleeve has left-handed external threads adapted to be threadingly engaged with mating left-handed internal threads of the nut, and a clamping portion adapted to be connected to the nut via frictional drag and rotatable relative to the bolt when said frictional drag has been overcome, such that the bolt when being rotated causes the compensation sleeve to rotate so as to be unthreaded from the nut. When the compensation sleeve has engaged the first structural member, the frictional drag will be overcome, and the bolt can be threadingly engaged with right-handed internal threads of the nut or the compensation sleeve for clamping the first and second structural members together. As a result thereof variations in the spacing between the first and second structural members will be automatically compensated.
