Product Reviews

Nothing beats a screw, Ha you know nothing I have been gluing and screwing my floors down since the late 90s and I have never seen a product like this if you nail properly I would say this product is the best I've ever seen you will not get floor squeaks and with todays house trying to eliminate voc's how about none great for home owners and the environment . PS if you wait for glue to dry it will harden and leave a space between joist and plywood and you will create floor squeaks

I thought these were glorified ring-shanks as well but after review they definitely aren't. The design of these nails allows them to twist as they go in to the floor joist sucking the plywood down with it. The teeth on the nail keep them from backing out. I would challenge anyone to try and pull one out. All that's going to happen is the head will break off. The plus to screws is that you know when you've missed since the screw head won't suck tight. Nails are more difficult to tell when you've missed.

Nothing beats a screw. This is a glorified ring nail. Screw are torqued in which pulls the subfloor down towards the floor joist. If the carpenter does not adjust the preasure of his nailer properly the nail doesn't get set properly.(In production homes this happens often). This product is better than just a standard nail. The best system would be to glue and nail sufloor, and right before the finished floors go down, screw all the plywood down. This allows the subfloor time to dry, shrink and settle.
