While parting out these rusty relics I fight small rusty screws often. I’ve tried several things even drilling the screws. Using a small punch & hammer to turn the screw. For example the wheel lip trim. Often 5 small screws. 3 come out easily but the others are stuck & rusty. Can’t get a good bite with a Phillips. So off comes the wheel so I can spend the next hour removing the two remaining screws. Is there a tool anyone knows of that that actually works to remove rusty screws.
 
how about spraying some liquid wrench, letting them soak for a bit, and using a screw extractor?

- you might wanna skip to the 5 mins mark..
from what I understand you're having trouble with..this might help?

or cutting a notch into the screw and using a flat head?
 
I now make my own penetrating oil. 50/50 ATF and Acetone. I believe it works better then any other penetrating oil I've used.

Yea I’m not talking about stuck screws. I’m talking about screws that have damaged heads that a philips screwdriver won’t work. There’s not enough head left for the screwdriver to bite to. I have a drawer in my tool box full of screw extractors & high speed cutting bits. Impact drivers, Center punches etc. that’s what I’m using now. I was just wondering if there was something else out there because drilling a hole in a rusty tiny screw head is a PITA & usually results in a broken off screw head then out comes the punch & hammer to try to drive it around & screw out. I’ve spent hours on one tiny screw.
 
Penetrant, I prefer Kroil and some patience before even putting A screwdriver to it. I soak things down the night before if I can.

Bob, have you tried using a JIS (Japanese Industry Standard) screwdriver? They are cut straight and designed to not cam out like a standard Phillips. It won't be a perfect fit but it seems to work a little better for me.
 
I usually pound the head down a bit with a hammer then pound a Phillips screwdriver into the old grooves. Tap the back of the screwdriver while trying to loosen it and it should come out, the hammering effect usually loosens the screw up. You won’t get all of them but it works most of the time. Make sure you use an old screwdriver.

No I have never heard of that. Where do you buy those

I’ve filed the head down trying to get vise grips on they. Moderate success. Still a lot of work.

I've had success with reaching around the back and grabbing the body of the screw with a small pair of vise grips.

Pretty much anywhere that sells tools. I know ACE, Lowes, and maybe Autozone typically have some on the shelf. Most people around here don't know about JIS. It's something that I learned about working on Honda cars and Kawasaki 4-wheelers. Personally, I've come to like it better than any phillips as they don't cam out and can handle more torque.

And if you ever see a screw with this dot it's cut JIS.

You know I have some Phillips screw drivers that I’ve filled the tip down so it will grab better. I imagine that’s serves the same.

It might. But the flutes of the phillips will still have the radius/curve that causes it to cam and back out. The JIS is cut straight in the flute area. Besides, you can pick one up for about $5.
