Rather than nails, screws are best to use for subfloors — these fasteners are convenient, easy to remove and capable of providing torque that nails lack. Because of their structure, screws can penetrate plywood more easily and improve the connection, whereas nails can weaken the plywood.
Nails are your best bet for subfloor because a pnuematic nailer can move hardware faster and cheaper than screws. Also, nails allow for more seasonal movement than screws.
I like to screw down subfloor using a stand up cordless auto feed system. While not as fast as nailing off a floor, it is easier on the body and reduces squeaks. For a two person crew, one framer glues and sets sheets while the framer fastening can usually help pack material and fasten sheets.
Screws are preferred and should be 3/4'' - 1'' long with a bugle head course thread type, similar to drywall screws but made for decks or flooring since drywall screws can not take to much torque and will break off at the heads. You also don't want the screw length to go through the subfloor.
Don't use nails. Screws are far better. 1. If you ever want the boards up again its easier. 2. Screws never cause squeaky boards like nails do. Trust me, its worth the extra effort.
Nails are generally recommended over screws for several reasons. Structural nails, such as galvanised or stainless-steel nails, are specifically designed for use with joist hangers. They provide the necessary shear strength to support heavy loads and resist the forces acting on the joist.
A screw is better than nails as it holds the things better than a nail. This is due to the presence of threading in screws that grips the surrounding material tightly. Also screws are easier to control than nails and can be removed easily.
You may think that any screw will do the job for securing subfloor, but that's far from the truth. You need to use the right fastener to ensure a long-lasting grip. PAMFast AutoFeed Screws are the preferred choice for interior and exterior subfloor.
As far as nails go, ring shank nails are a popular choice for subflooring. A ring shank has extra grip and holding power, compared to other shank types, and creates a tighter subfloor. Although ring shank nails have a good hold, screws have more overall holding power by comparison.
Before securing the second layer, ensure that it is properly aligned and that there are no gaps or misalignments between the sheets. Use construction adhesive and screws to secure the second layer to the first layer and the joists, following the manufacturer's recommendations for fastener spacing and placement.
Using code-approved screws rather than nails is the best option for avoiding movement. If using nails for subfloor installation, stick with ring-shank nails; smooth nails may withdraw easier, leading to squeaks.
For traditional plywood flooring installations, where the plywood is directly attached to the subfloor, the recommended plywood flooring thickness typically ranges from 5/8-inch (15mm) to 3/4-inch (19mm). While 3/4-inch plywood is standard for most residential subfloors, certain conditions may require thicker plywood.
Subfloor. Screw spacing should be 6" o.c. at the boundaries and 12" o.c. in the field, assuming an unblocked diaphragm. For blocked diaphragms increase the numbers of screws by 15%.
Framing nailers are the best nailer for construction work. Heavy-duty design for framing work, decks, fencing, subflooring and crate building. Can use 2-inch to 3-1/2-inch coil or strip nails. Available in pneumatic or cordless models.
Use 1-1/4-inch screws for basic tasks where strength is less of an issue or when attaching two 3/4-inch-thick boards across the grain.
Rather than nails, screws are best to use for subfloors — these fasteners are convenient, easy to remove and capable of providing torque that nails lack. Because of their structure, screws can penetrate plywood more easily and improve the connection, whereas nails can weaken the plywood.
Plywood is considered the most popular material used for subflooring, it has been used since the 1950s and remains one of the top choices for contractors. Standard plywood works perfectly fine as a subflooring material, but the best option is ¾” tongue-and-groove plywood subflooring.
Because the wood expands and contracts as a reaction to moisture, nails provide a more flexible fastening job.
Wall studs are nailed vertically to the bottom wall plate, and the wall plate itself is nailed (downward) into the subfloor, with nails even extending into the joist. All items except underlayment and floor covering rest under and are nailed to the bottom wall plate.
#8 or #9wood screws X subfloor thickness +1 inch.
The strength and solidity of floors are essential structural elements of all buildings. When flooring is installed, subfloor adhesive is applied below the panels to secure them at the panel-to-joist connection, which minimizes squeaks and prevents uneven flooring.
The exterior threading results in areas of thin metal that can easily break when exposed to stress or pressure. Nails don't have a threaded shaft, so they aren't as brittle as screws. And in turn, they offer greater tensile strength, making them desirable for construction and carpentry applications.
Should I use Decking Nails or Decking Screws? Decking screws are better than nails when building a deck. Decking screws hold down your decking more securely than nails and will stop your decking from warping. Also, you can easily remove screws for deck maintenance without causing damage.
