A device for operating on each nut of a double-nut assembly, wherein an inner nut of the assembly is of a diameter larger than that of an outer nut of the assembly. The device comprises two components: the first component is provided to act on the inner nut and is designed to allow a portion of the second component to pass therethrough, while the second component is provided to act on the outer nut. The first component may be used to rotate the inner nut to a desired position while a portion of the second component resides therein, whereafter the second component may be used to secure the rotated position by tightening the outer nut. The device may be used with an eccentric fastener assembly employing such a double-nut arrangement to set the toe angle of a vehicle wheel.

The method as in claim 6, including the step of forming the inside tapered collet as an integral part of the metal body. 8. The method as in claim 6 or 7, including the step of welding the outside tapered collet to the measuring tube. 9. The method as in claims 6 or 7 including the steps of: mounting the outside tapered collet on a metal jacket, and firmly attaching the metal jacket to the measuring tube. 10. The method as in claim 9, including selecting the length of the metal jacket to be only slightly greater than the length of the bore in the metal body and the outer diameter of the metal jacket to be significantly larger than the outer diameter of the measuring tube. 11. The method as in claim 6 or 7, including the steps of: flush-mounting a ring, preferably consisting of copper, on the inside surface of the outside tapered collet and/or on the outside of the inside tapered collet, and applying the pushing force by way of said ring. 12. The method as in claim 6 or 7, wherein said pushing step is accomplished with the aid of a screw coupling. 13. The method as in claim 6 or 7, including the step of forming the outside tapered collet and/or the inside tapered collet of titanium, steel or stainless or alloy steel. 14. The method as in claim 6 or 7, including the step of coating the inner surface of the outside tapered collet with a filler material preferably consisting of a metal such as silver or a synthetic material such as PTFE. 15. A method for mounting a metal body on an essentially straight titanium or zirconium measuring tube of a Coriolis mass flow meter, said method comprising the steps of: firmly engaging a metal jacket around the measuring tube; pushing a tubular metal body having an inner surface onto the metal jacket; pressing the metal body inward directly against the metal jacket, and welding the metal body to the metal jacket. 16. The method as in claim 15, including the step of welding the metal jacket to the measuring tube. 17. The method as in claim 16, including selecting the length of the metal jacket to be only slightly greater than the length of the inner surface of the metal body and the outer diameter of the metal jacket to be significantly larger then the outer diameter of the measuring tube. 18. The method as in one of the claims 15 to 17, including the step of coating the inner surface of the metal body with a filler material preferably consisting of a metal such as silver or a synthetic material such as PTFE. 19. The method as in one of the claim 1, 6 or 15, including the step of forming the metal body of titanium, zirconium, steel or stainless or alloy steel. 20. The method as in one of the claim 1, 6 or 15, including the step of forming the metal body as a retaining collar for an oscillator or a process-variable detector or a part of an oscillator or process-variable detector.
