With that said, it's imperative you choose a fastener compatible with your subfloor thickness and material. The quality and correct type of subfloor fastener can literally make or break your floor.
Also know, should you screw down a subfloor?
Second, you want to make sure the subfloor is properly glued and screwed to the floor joists; if it's not, there will be squeaking and creaking. When you use a nail gun to attach subfloor sheathing to the floor joists, the nail sometimes misses the joist. Remember, nails can pull up; screws don't.
Subsequently, question is, how do you nail down a subfloor? Generally, nails (6d ring or screw shank, or 8d common) should be spaced 6 inches on center along supported panel edges and 12 inches on center on the panels' interior supports, or as specified on the construction drawings.

What screws to use on subfloor?
Steel Screws The proper steel screw sizes for securing 3/4-inch plywood to the floor joists are #8, #10 and #12 screws. The number refers to the thickness of the screw. Each is available in lengths from 1 1/4 to 3 inches. Typically, the 3-inch variety is used to secure plywood subfloors.Do I need to glue plywood to subfloor?
On the 3/4" subfloor, you have the right idea. Use subfloor adhesive, and screw 8" at edges, 12" in field. For the 1/2" underlayment, ideally, you want to screw every 6" all across the panel. Adhesive will help you here, as the subfloor plywood will have voids in spots that will not hold a fastener.How many layers of plywood do you need for a subfloor?
Floating subfloor: There are two common methods for this. The first is to lay two layers of 3/8-inch plywood over the slab without fastening or gluing them to the slab. One layer is laid, and the second layer is stapled or glued perpendicularly or diagonally over the top.How thick should a subfloor be?
Typically made of plywood or OSB and ranging in thickness from 19/32" to 1 1/8" thick, the subfloor is truly structural, second only to joists in this respect. Subfloor holds up all of the above layers of flooring, as well as everything in your house—people, dogs, cats, pianos, furniture. All houses have subfloors.Can I use drywall screws for subfloor?
Drywall screws should only be used for drywall, and a temporary coat hanger. You want more strength and need less space for the threads to secure the subfloor.

Some sanding may be needed when it sets completely.How many screws do I need for a 4x8 subfloor?

Do you need to glue subfloor?
Glue. Although using a subfloor adhesive is not required by code, it is a standard practice that can help prevent floor squeaks by reducing the chance for movement at the panel-to-joist connection. A quality subfloor adhesive will also increase the overall stiffness of the floor.Does subfloor go under walls?
Moisture trapped under a building's walls often rots the subfloor. Left alone, the moisture eventually destroys the joists below, and the wall's plate above, the subfloor. A rotted area of the subfloor often extends under the wall.Should underlayment be glued to subfloor?
