The combination of clinch nut and spacer/ washer is a field-proven and patented setting process from MDS | AUTORIV. This process is ideally suited for assembling in extrusion profiles, in very small installation spaces or hard-to-reach places.
For the setting in closed profiles and for processing in spaces that are difficult to access
Suitable for the processing:
- in extruded profiles
- in limited installation spaces
- in spaces that are difficult to access
- Tried-and-tested and patented setting method
- Freely variable dimensions of clinch nut and spacer/ washer
- Fully-automatic, reliable processing
- Cost savings due to one-stage processing
- Various custom solutions possible
Advantages of the combination of clinch nut and spacer/ washer
- The stability of the combination is a lot higher compared to the blind rivet
- Spaces that are difficult to access (e. g. closed aluminum profiles) can be processed
- Patented setting procedure close to serial production without opening the profile
- The rigidity of the component is maintained
- Setting of several fasteners combinations at the same time - shortened cycle times
- Setting of two elements in one step (nut and disc)
- Application in aluminum profiles from 2 mm wall thickness, depending on the individual application
Application comparison: Blind rivet / nut-disc-combination
MDS innovation for high-strength applications compared to common solutions.

- Limited stability
- Hardness of the element
- Stability dependent on the screw joint
- Low pulling force
- Small contact surface
- High stability
- Hardness is freely selectable
- Independent from the screw joint
- High pulling forces due to:
- adjustable geometry
- large contact surface available
- no setting behavior
Wall thickness > 4,5 mm
- Also available as an individual part for small sheet thicknesses
- Low height
- Flush fitting
- High pulling force
- No setting behavior
Wall thickness > 2 mm
Fields of application for the combination of clinch nut and spacer/ washer
- Suitable for the processing in extruded profiles,
- e. g. electric cars, crash boxes, module carriers
- Processing in very small spaces
- Processing in spaces that are difficult to access
- Utility vehicles / agricultural machines
- Battery trays in electric vehicles
- High-strength screw connections
- Components with undercut or overlap
- As stop surface and chemical isolator
- Mainly for the application in aluminum components
- Other materials are available upon request at any time
