A method for producing and installing a fastener, including the steps of forming an engaging portion having a projecting stem which is interiorly hollowed over at least an intermediate extending range, the stem including a solid end most extending portion, and forming a receiving portion having a surface, within which is configured an inner rim defined edge, a diameter of an aperture between said rim edge being less than a diameter of the stem. Additional steps include pressing the solid end most extending portion of the engaging portion through the inner rim edge of the receiving portion and aligning with the inner rim edge a location of the interiorly hollowed portion of the stem, causing inward collapsing of the aligned location by the rim edge to secure the engaging portion to the receiving portion.

A blind riveting device is provided, which is adapted for engagement to a handle having a powered translating member projecting therefrom. Force from the translating member imparted to a drive piston moves a second piston to pull a blind rivet connected to a jaw engaged with the second piston, thereby mounting the blind rivet.

A functional element having a section that has a flange, that projects away from a side of the flange, and is adapted for an aperture-free punching into a sheet metal part and having a shaft part that projects away from a side of the flange opposite the first side, that satisfies a function and that is provided with a longitudinal axis. The flange and the section are arranged at least substantially coaxially to the shaft part. The section is formed as a hollow cylinder that has notches extending in parallel with the longitudinal direction at at least one of its outer jacket surface and its inner jacket surface. The section has a diverging frustoconical shape that runs out at least substantially at the free end at the inner side of the section in the region of its free end and that serves for the widening of the section on the punching in the sheet metal part. A component assembly and a method of producing the latter is also claimed.

A crimping system of a fastening component onto a support, including a crimping tool comprising a housing and a traction rod configured to cooperate with the fastening component so as to deform the fastening component when a translation of the traction rod takes place, a fluid source connected to the housing to supply a fluid under pressure to move the traction rod, a sensor to measure the movements of the traction rod, a detector to provide a pressurisation information of the fluid in the housing, and a control unit configured to record a curve of the measured movements and the pressurisation information of the fluid in the housing.
