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 mounting bolt, a base element, and an adjustment sleeve. The adjustment sleeve has a drive portion adapted to be engaged with the nut by frictional drag and rotatable relative to said mounting bolt when said frictional drag has been overcome. The drive portion comprises an internal annular plastic portion which projects from the wall of the adjustment sleeve radially outwards sufficiently so as to frictionally engage the threads of the mounting bolt to provide for said frictional drag.
