So usually you don’t just pull up a sub floor and decide to replace them. (Unless there is water damage that comprises the sub floor). Subfloors are usually glued and screwed down, and you might run into issues removing screws already If you had to remove it. With this product your really only tighten down a few spots in between well connected sections so you usually won’t use alot. The way it works is you can use the tool and screw the screws in and then with the tool snap the head off just below the surface of the sub floor so it doesn’t poke thru the carpeting or interfere with laying down vinyl or tile etc. if in the rare case you remove the sub floor and it can’t be pulled up with a pry bar (as the sub floor would be weakened) you could just cut the very few of these with a reciprocal saw. If you have squeeks, and can’t access underneath the floor from below,(I.e. there is a ceiling below) these are a great fix for tying down those squeaky spots. Hope that answers it for you!!
I screwed the subfloor through the linoleum into a joist just as the directions said to do and it worked just fine.
how many screws
I've only used this on plush carpet so I can't say for certain that the pile won't pull on barber carpet where the pile is much tighter together. You could test it in an inconspicuous spot (like a corner or closet) to see how the carpet reacts. The screw will be countersunk underneath the floor once finished and you should not see it after you've finished installing it.
I would think that would be wise since these screws are made for wood and not metal
May be not out, but use a small grinding wheel in a hand held grinder. Don't forget your safety glasses
I used an electronic floor sensor. It was able to sense enough to help. Since my floors were 1 1/2 inch thick it was hit and miss but it helped a lot. I then used a very small drill bit to drill 1.6 inches deep and used a straightened paper clip in the hole to make sure I was on the joist. Wood filler filled all holes which are now basically undetectable.
I used a cordless drill and it worked fine.
