Rated 4 out of 5 Great Corrosion Resistance
I've used a couple of thousand of these in outside jobs (not just this size though). I used them to make rabbit enclosures and after two years they show no signs of corrosion (see picture). They drive well into treated wood and i've only had one failure (this size) though I think I hit a particularly tough knot and the head sheared. I've also used them in rawl plugs around a pond for netting and these too have not corroded unlike some standard screws i used.
The only downside of these is they are quite expensive.
Can't really say much more about a screw, but if you are looking for a screw which will not deteriorate in outside conditions i recommend these A2 screws.

These screws are expensive but they are great to use and will drive into softwood with no pilot hole. You will still need a pilot hole in hardwood. Used outside, they dont rust so can be removed if required in years to come. I like them a lot and would use these in preference to any other screws.

Years ago I used to use Brass screws for outside use but you had to be careful as they can be a bit weak and snap. Since using these Turbo Ultra Screws in stainless steel I have had no problems as they are stronger and you know that the screws will undo and can be reused again several years after first fitting. Nothing is more annoying when trying to remove a rusty screw that is ceased up or shears off and using these screws eliminates these problems.

Very disappointed. Bought these screws over others as looked the business, even though they were more expensive. Screws drove in very easily. And first impressions were good. But when I tried to remove screw 50% of them snapped! the heads sheared off clean making the job twice as hard as it should have been. The screws had only been in the timber 10 min!
