Worked perfect for furring out 2x’s on an old log cabin, some logs were very old and tight, screws could withstand all the torque from the hammer drill to get all the way in

I recently used these screws for my sunroom addition, and I couldn't be more pleased with their performance! These screws are incredibly strong and reliable, providing the stability I needed for such an important project.The installation process was straightforward; the screws drove in smoothly without stripping, thanks to their sharp threads. I appreciated the robust design, which gave me confidence that my sunroom is built to last.Additionally, the corrosion-resistant coating ensures that they will hold up well over time, even in varying weather conditions. I’m also impressed with the variety of sizes available, allowing for precise application in different areas of the construction.Overall, these structural wood screws are a top-notch choice for any woodworking project. They made my sunroom addition not only easier to construct but also added a layer of durability that I know I can rely on for years to come!

I like these a lot. They are just about as strong as lag bolts and much easier to install. They are also heavily coated so I believe they will hold up well in pressure treated wood. But only time will tell for sure. I built my porch with them and I am comfortable with my whole family out on the porch so there’s that. My only beef, about 15% of the screws are not quite straight. They still work but they are a bit crooked. I’d rather not have that.

This are heavy duty screws. The coating appears adequate and the threads are quite sharp to help with installation of long screws. Since they are structural screws the material used is quite important. I have no way of confirming the technical performance, but can say they are durable - haven't broken one yet.
