Have you ever had a screw stuck that just won't come out? I have and yes, I've done what everyone else has probably had to to before. Get the dremel out & cut a slot in the head (and my chassis) and get a large straight head screwdriver out and "hope" it comes out before you torque the head of the screw off.
Well, I tried something last night that worked great!! So next time you have a stubborn screw try this!
#1) If it doesn't come out naturally....DON'T force it!
You'll just strip it out....
#2) Put a drop or two of WD-40 around the head of the screw (where you can see the edge of the countersink)
#3) Wait about 10 minutes.....
#4) Take your soldering iron and heat up the head of the screw for about 1 minute...... the oil will boil around the head and it'll loosen up the threads.
THEN>> Give it a good TWIST! and walaaaaa! It should come out...
If not, heat it up for another minute and try again.... but remember Don't force it.... it'll eventually work. It did for me...!
Hope this helps someone out there!!!
