METAL SHEET, METHOD FOR FIXING SAID METAL SHEET BY FLOW DRILLING AND ASSEMBLY COMPRISING SAME

摘要

The invention concerns a flow drilling and tapping method for assembling thin metal sheets. A tubular extension (12) produced on said metal sheet comprises a conical mount (18) at said metal sheet (10). Through said mount (18), advantageously provided with a hexagonal base (24), the loads are transmitted along the tubular extension (12), and it is possible to fix a perforated element (1) on a metal sheet (10) having a thickness less than 1.5 mm and to apply a standard tightening torque.
