If however, only one side is accessible, then the well- established direct screwdriving flow form principle comes into use.


Innovative screwdriving system


for vehicle bodywork production A flow form screw is positioned on an aluminium or steel sheet wihout pre-drilled holes and the screwdriving process begins. The screw is applied with a high pressure down-force and rotates at high speed, generating a frictional heat which forms a crater through which the screw’s thread passes under reduced pressure. A machined thread is created, a normal screw can also pass through in case of repairs. After the flow passage has been formed the speed is reduced and the screw is tightened to the head connecting surface and then the final tightening of the fastener to the pre-deterined parameters of torque and angle takes place. The entire procedure usually takes
