Rated 4.3 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by The Best that's way above the rest I build decks of many sizes and materials. For Cedar the Trio is GREAT!! July 2, 2015
Rated 5.0 out of 5.0 by Far superior to DeckMate I have used DeckMate screws for quite a while; but never again. These TRIO screws cost about 25% more, but it's worth it. They don't make TRIO in 3.5" lengths and I was hesitant to try them because I've experienced other 3" screws that strip out the wood even before the screw head was all the way flush into the material; needless to say this is frustrating to deal with. The TRIO screws have threads that go up the shank much higher than other screws which I believe is why they perform so well, even close to knots the screw always pulled the head into the material with ease. The TRIO screws also do not split the wood so easily like other screws do. Even driving the screws 1" from the cut edge of the board I experienced no splitting (save one occasion when there was a knot, and the wood was partly split already near to where I needed to position the screw.) I'm not quite sure how it works, but the special shape of the head produces a clean finish around the head of the screw. The wood fibers do not flare out like other screws do. November 7, 2014
Rated 5.0 out of 5.0 Great Product This is a great product. The bits provided in the box are high quality and didn't spit the wood when I installed unlike most deck screws. The bits provided are high-quality and the drive system doesn't cam-out. Installation guide was helpful. Will buy again. May 15, 2013
