Hello, with my vehicle the front bumper is fixed with two 10 Inbus screws. Unfortunately, long ago the paintr had failed to renew it during installation (rule Audi) or at least with anti-seize paste. After 10 years now unfortunately by contact corrosion no more to loosen. The left screw I could tear off “fortunately” with a 1.5m lever in the thread, at the right is unfortunately the inner hex head turned round. To turn, or to transfer so much forces over the round head that the SChraube in the ideal case also peels off in the thread. To get to the head only with an extension through a hole in the bumper, so weld on or pliers also falls away. Torx also brought no success, 55 torx already too small, 60 torx too big. Do I get the necessary forces transferred with a screw turner that rips off the screw? Greetings from the Westerwald!
