Does anyone know the best way to get stripped or broken wheel locks off the cars my best method is with a 20mm and am wondering if there’s a better way

 

Weld a nut onto the end of them

 

I’m in a general service section and we don’t have time for welding I was wondering more if there is a better tool then a 20mm I’ve looked for removers haven’t found any and turbo sockets but 21 and 19 don’t work
