Application and function
Suitable for: Insertion in metal sheets with tensile strength less than 600N/mm². It can be used in galvanized, painted metal sheets
Sheet metal bottom: Flat without indentation, optimal fastening characteristics (clamping with a large surface area)
Pilot hole preparation: Pre-punched pilot hole according to AUTORIV specifications
Die: Use of a flat die (optimal downtimes)
Installation: Torque absorbers move and shape the material into the collar undercut
Outer diameter - pull through force: Medium outer diameter also suitable for aluminum applications, good pull through force
Under-head serration - torque: Strong under-head ribs for high torque absorption
Collar - push out force: Collar with undercut to provide push out forces
Highlights
Lower risk of warping of workpieces, especially with many setting positions
- Lower risk of warping of work pieces
- Flat sheet metal bottom with largest surface possible for the preload through tightening
- No diversity, less stock requirement
- No risk of mix-up (Incorrect fasteners in incorrect application)
- (Re-)use of existing automation / tooling, thus reduction of investment
Greater compensation possible with custom design
- Ensuring optimal pressing: No "Not-OK pressings" with risk of subsequent complaints and quality costs
- No frequent re-teaching of the robot necessary
- Ensuring high availability and output, thus cost reduction
