Abstract: A tolerance compensating assembly of automatically compensating tolerances in the spacing between two structural members comprises a mounting bolt 10, a base element 4, an adjustment sleeve 6 and a driver 8. The base element 4 and the adjustment sleeve 6 form a first thread pairing G1 of a predetermined spiral direction for adjusting the adjustment sleeve 6 relative to the base element 4. The base element 4 and the mounting bolt 10 form a second thread pairing G2 in the opposite spiral direction for clamping the two structural members B1, B2. The driver 8 is a separate structural member and disengageably connected to the adjustment sleeve 6 and has a plurality of flexibly resilient clamping portions 34 spaced along its periphery, which provide for frictional contact with the thread of the mounting bolt 10 above a predetermined torsional force.
