Good screws
Would RecommendGood screws. I did have a few heads strip out when I had to remove them and re-install them. But that could have been me since I was driving them at an angle but didn't know the exact angle when I pulled them out. The Torx bit supplied gets a little worn by the end of the box. One made out of slightly harder steel would be better.

Great fasteners
Would RecommendThese are great fasteners that work for just about every job. I bought them in all dofferent sizes and use them for anything from woodworking, to framing, to repairs around the home. They have a great non-slip star drive, and do a nice job of pulling pieces together as you tighten the fastener. Highly recommend.

superior product.
Would RecommendI liked that it was high quality, the design of the screw is better with the different section at the top that I think allows it to grip better than what I've seen of standard deck screws that are a long flat section only. It also comes with a star driver
