TurboUltra Woodscrews Double Self Countersunk 3.5 x 25mm 200 Pack is rated 3.6492537313432836 out of 5 by 134.
Rated 5 out of 5 by from Quality screws These screws are great for outside use but need a pilot hole and I find best to use impact driver as the heads can shear easily specially f they hit a knot or used on hardwood

Rated 5 out of 5 by from Weather Proof 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.

Rated 4 out of 5 by from 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.

Rated 4 out of 5 by from Good quality s/s screw Used to lay marine ply to a concrete floor ready for vinyl. Good quality screw with good strength and grip.

Rated 4 out of 5 by from Good with a little help. Good screws, nice self drilling and countersinking attributes but need to be screwed fast in one go. Screwing into tough, hard pine beams a few snapped. Needs a pilot hole and to be power driven in one continuous motion. If you stop part way they bind and snag.

Rated 5 out of 5 by from What more is there to say? It seems that everyone who has reviewed these screws loves them, and justifiably so - they're brilliant. Only criticism is that I had to buy 200 when I only needed 30!
