Avtronic® is a speed fastening assembly solution that is widely used for attaching connectors and components to PCBs, but it can also be used to attach a wide range of other connectors and electronic components.

The Avtronic® rivet has annular body grooves which expand radially during insertion. This provides a vibration-resistant joint and good pull-out resistance.

Various body lengths provide a wide grip range to accommodate most combinations of connector and PC board thickness. The Avtronic® can be used in blind hole applications and is an ideal tack rivet.
