Bollhoff Fastenings has announced the introduction of a new pneumatic setting tool, to a market where many millions of blind rivet nuts are being used to place a reinforced thread into sheet metals, profiles and hollow sections. Now using automatic force-control when 'pulling-up' the fastener from one side of the workpiece, the new design employs a pressure sensitivity on the tool stoke, in order to ensure a totally consistent setting, even when faced with a variable material thickness.
