    Patent number: 5259689
    Abstract: The invention relates to component connecting fastener especially flange connecting fasteners for the propeller shaft in a motor vehicle. The two flanges 4, 5 contain bores 8, 9 which align with each other. Axially slotted tensioning sleeve 10 is introduced into each bore 8, 9. The tensioning sleeve 10 is axially elongated and radially expanded by tensioning pin 22 driven into bore 12. After completion of the assembly operation, contact face 17 provided at collar 16 is supported on contact face 18 of flange 4, with supporting face 20 being supported on abutment face 21 of further flange 5. In this way it is possible to automate the assembly procedure while requiring less space and achieving a higher compression between flanges 4, 5.
