will these work on 1/4" corroded stainless steel screws?

I just tried to use them to remove some 1/4-20 stainless flat head screws that were corroded into a piece of aluminum. The #2 tool, which is spec'd for 1/4" fasteners, broke with very little effort. Since the heads were big enough, I then tried to use the #4 tool, which is supposedly strong enough to remove 3/8" fasteners, and it broke too. I don't expect miracles from these tools but I do expect that they would strip the fastener head before breaking themselves. I consider this a design flaw and would not recommend them for really tough jobs.

I can't figure out what grade bolts are for license plates. I have 4 of them with broken heads. Is this kit strong enough?

license plate bolts should not be any heavier than grade 4These extractors are the greatest, I removed broken steel bolts that the head had stripped out-follow the instructionsthey are amazing!!!!

Need this to take the bolts out from my fender. Is this strong enough?

They should be strong enough, I have never had a problem with any of the Grabit products. I have used it to pull out stripped bolts off my old motorcycle.

I have an interior threaded pipe I need to remove that is th edrain for my air compressor. I snapped it off. It's inside diameter 5/16".

5/16 is too large for these, a standard extractor is tapered it's entire length, these aren't.
