I guess some can be stubborn...Not had a problem with a drum screw, but had the door hinge screws resist impact driver, drill bits burning them out...resorted to welder on them
It's the heat of the welding that freed the screw, not the technique of welding on the bolt. The only way to get them out for years was to put the gas welding torch on them, a bit of diesel to cool and they unscrewed.
Just do what everyone did for years, drill the head off.
The screw is there to stop the drum falling off. It must be in the factory during production, as they would never fall off changinfg the wheels.
