When a customer application needed three rivet nuts to mount the rear windscreen motor onto the tailgate so as to create a weather resistant and anti-rattle joint, GESIPA® designed an M6 square bodied rivet nut with a special chamfer and coating on the flange for easy side by side placement of three rivet nuts into the application. Stephen Dovernor, Technical Account Manager explains "A square bodied rivet nut is used in applications to allow extra security during the assembly process when compared to a round bodied rivet nut. It provides high torque-to-turn values in applications giving a highly secure joint. Also, when on assembly line there are chances of mistaking a set rivet nut with a weld nut. Thus a square bodied rivet nut helps to distinguish it from a weld nut hence resulting in minimal operational failures."
CAD models were initially used to check the working parameters of the nuts and consequently first samples went onto the assembly line after passing all the required tests.
