A tool for inserting or removing a tang-free wire thread insert is described, the entraining blade of which is manually fastenable and replaceable within the axial recess of the spindle body by means of a latching connection. In addition to the secure removal of wire thread inserts, this tool construction also ensures a quick replacement of worn entraining blades of the tool. Furthermore, a production method for such a tool is described.

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.
