First punch or drill the correct size hole. DO NOT deburr the hole prior to installation as this will remove material required during the clinching process. It is preferable to install the fastener from the side of the panel with the burring or blow through.
Place the fastener in the hole like in the diagram above making sure the part is seated squarely. Apply a parallel squeezing force until the head is embedded flush in the panel.
When installing Self Clinching fasteners, please pay attention to the minimum hole centerline to edge and parent material hardness limitations.
