You might want to try using a mixture of 50% acetone mixed with 50% automatic transmission fluid and soak real well. Word of caution - acetone loves to dissolve rubber to be cautious. Cutting a slot with a cutoff wheel and screwdriver will add to the torque you can apply. After it is soaked, try tightening first before loosening.
Good luck, Jim V.

Some of you have been there. Have worked all day and have 7 screws our and three with ruined heads (cammed out) which I can't get out. The problem is rust. I am using a fresh clutch head bit in a 1/4 inch drive ratchet. I don't have enough power in my hands to use a straight driver. I douse each screw several times with Kroil penitrant. I take it slow and use as much downward pressure as I can. Some are so frozen that either the bit starts to twist or the bit cams out ruining the screw head. I tried Alden Grabit bolt and damage screw extractors to no avail. I tried drilling but the screw head is really, really hard. I dull a fresh HSS drill in about 20 seconds. Should I buy a left hand drill? A carbide drill? Should I use heat on the screw head? Should I take a die grinder and carbide bit and grind off the head and hopefully deal with the remaining stub somehow? Has anyone here been there - done that?
