Looking for tips to loosen stubborn screws

[SquareTopCollector]

I am replacing the hinges on a bottle door and the darn screws wont move. If the screws were anywhere else on the machine I would have drilled them out but since there is glass behind these screws its a delicate matter.   Any suggestions? 

Blow torch, hammer drill?

Gently tap your screwdriver with a hammer, also sometimes it works to turn them clockwise before turning them counter clockwise, heat sometimes works, as with PB Blaster, Liquid Wrench etc. Good Luck!!!

What Joey said....

and... Some of the ST machines actually use bolts not screws to hold the bottle door. If you have one of these machines getting to the nut will let you work both the nut & bolt for more leverage. If you dont' there's a good chance that when you finally loosen them they spin unless you get to the nut.

Thanks guys. The door is already off. These are the small screws that hold the hinge to the door.

I have had good luck slotting the screwhead with a Dremel Cut-off wheel and then it usually unscrews fairly easy.

Are the heads countersunk?  Or are they just normal sheetmetal type screws?  If you can access the heads you can grab them with a pair of pliers and start to twist them out.  I have a pair I got from Snap On that are small and will put the "death grip" on the part.  They have really sharp teeth that dig into the screw really well.

There is also a tool you can get at sears I think it is called a drill out.  It basicly is a reverse drill bit that digs into the screw and grabs it to make it spin.

Here is a link on the pliers.
