what kind of screws to use on subfloor
Plywood and OSB are two of the common materials in subfloor construction. Many people utilize nails in plywood and OSB subfloor, but nails oftentimes do not create a tight connection. Screws are the best to adhere subflooring and minimize deflection. But with the many types of screws, what screws are best to use on subflooring?
There are many types of screws for plywood and OSB subfloor. You lot'll desire to use #8 1-1/ii inch forest screws spaced eight inches autonomously to secure a v/eight″ OSB subfloor to the floor joist or flooring truss. For 3/four inch plywood, it would exist best to step upwards to a 2-inch wood screw to account for the added thickness. You can likewise employ screws to remove a squeak in the subfloor caused by the subfloor moving confronting the nails.
Choosing screws requires due diligence. It'due south more than only walking to a hardware store and picking the materials. We'll explain in depth the disquisitional considerations in this process.
Thus, for more insights on plywood and OSB screws, go on reading.
Subfloor: Screws or Nails?
Screws are ameliorate for a quality subfloor chore than nails. Screws create stronger joints and are likewise less subversive. Hammering nails volition destroy the soft plywood or OSB. It will result in weakening of the articulation and ultimately creaking of the subfloor.
The allure of using nails in a plywood or OSB installation is quite strong. Nails are relatively easier to employ. With an air nailer, yous can drive in multiple nails at 1 instance. Thus, for many people, it is the most convenient option. Also, nails are relatively cheaper than screws. Therefore, working on a tight budget has a natural propensity to opt for nails over screws.
Still, you should opt for screws over nails despite these advantages. Screws take the added do good of non backing out and causing flooring creaks when walking on the floor.
Here are some of the reasons why screws are better than nails:
ane. Torque
A plywood floor ought to be quiet at all times. Unfortunately, experiencing an occasional creak is e'er in the offing with nails. The secret formula of the tight joints with screws is threaded. Therefore, they firmly hold into the plywood or OSB fabric, leaving no room for looseness.
Every bit the screws bite into the forest, they provide some unachievable torque from using nails. Hence, if at that place is weakness in the plywood, it will be solved past the torque of the screws.
When using nails, the opposite happens. Rather than improving the connexion, there is a high likelihood of weakening the plywood. Using nails without an air nailer will also prompt yous to hammer them into the plywood. Past doing so, you introduce weakness into the joint. After some time, the plywood will starting time moving equally the binding joint is already loose.
2. Easy to Remove
Sometimes in the future, you may want to remove the board or supersede some parts. In such a case, screws volition facilitate easy removal equally yous'll but demand to unscrew them with a drill.
Even if you make a mistake during installation, it can remove screws. Notwithstanding, removing nails can be boring and damage the subfloor material if you're not careful.
iii. Convenience
At that place are fewer improve connecting components in woodwork than screws. Due to their structure, they tin can easily penetrate the plywood without requiring excessive strength.
Nosotros, therefore, recommend the utilize of screws over nails at all times unless it's near inevitable. It volition toll more than and likewise requires more expertise to install screws, only it will be worth all the investment as your subfloor will be creak-proof for then long.
How To Choose The Right Wood Screws
We've explained that screws are head and shoulders in a higher place nails in plywood subfloor projects. You are now probably wondering if you can use just any blazon of screw that is readily accessible.
Material
You'll come across screws made of steel, statuary, brass, or aluminum in the market. Most of the ordinarily used screws in woods projects are steel-made. The material is difficult and creates tight joints, thus the immense popularity in plywood subfloor projects.
Steel screws are also not overpriced despite their significantly high value regarding force and durability. They are likewise available in a diversity of sizes. Therefore, you should settle for steel screws for your plywood project.
There are also other critical considerations, such as tapered or not. A tapered spiral is popular due to its high tenacity under intense pressure level. If the plywood is quite dense in thickness, you lot can use a number 8 weight drywall screw. They are sturdy and relatively cheaper than the erstwhile-fashioned tapered screws.
Cull a Bulge Spiral Head
You also need to pay attention to the caput of the spiral as it's a vital determinant of the final outlook of the plywood project. Some will sink flush while others cannot. Depending on your preference, cull your ideal kind.
Burl head screws are ideal for attaching subfloor to the floor joists. The bugle head countersinks for a flush finish with a smooth underlayment for finished flooring.
Some other upside is that information technology does not require drilling holes. Drilling is time-consuming, and if y'all tin can notice a manner of bypassing the process, the better. The screw diameter is approximately ¼-inch and thus penetrates through the plywood surface fifty-fifty with no hole. The aspect is also key to solid joints.
The head is countersunk and features a concave convention to facilitate like shooting fish in a barrel sinking into the plywood. Information technology too aids in stress distribution which is paramount for a healthy articulation. Such screws are ideal for drywall projects and plywood subfloors.
Choosing the Right Head Type
Getting the right kind of bulldoze likewise goes a long way in determining the strength of the joint. The drive dictates how the spiral will move inside the plywood'south surface. Thus, it has everything to practice with torque distribution during the screwing process.
Philips Head Drive
Named after American businessman Henry F. Phillips, the screw fits the screwdriver easily. Its shape means that the commuter introduces immense torque. Since the driver bits or screwdriver hands comes off, the screw caput breaking diminishes.
Thus, exerting actress torque across a particular threshold will counter the driver's movement with the Philips design. It will exist pushed outwards rather than farther in, which would break the spiral caput.
It is not the ideal spiral for plywood DIY projects. Nonetheless, if you are looking for an actress tight joint, the bulldoze will evangelize precisely that. One problem with Phillips bulldoze screws is that they tend to strip, making them difficult to remove.
This leads usa to Torx drive screws.
Torx Aka "Star" Bulldoze
Torx drive screws are US-made and improve the square drive kind. While the Robertson features iv contact points, the Torx has half dozen. Thus, the driver has a firmer grip on the screw facilitating the commitment of extra torque.
It thus forms tighter joints than all the other three screw drives. However, the Torx does not prompt the commuter to come up out similar the Robertson drive. Hence, in that location is the hazard of the screw head breaking.
Due to the extra torque that the stardrive assets, information technology is ideal for use on dense plywood. The extra torque on the plywood will drive the screw farther inside, enough to make the head countersink.
Also, note that there is little chance of slipping due to the increased contact area. Thus, driving the screws out when necessary is far easier than for the other drives. Y'all might need to do this at some point when y'all want to replace your subfloor.
If you lot opt for the Torx drive, you'll spend more than an average Philips bulldoze screw. However, the price is worthwhile for a screw that delivers actress torque.
Form Thread
The spiral part of the spiral that enters the plywood during installation is the thread. Note that at that place are different types of threads, but in our instance, we are only interested in the roughness or the smoothness flake.
It would be best for the plywood project to settle for the coarse threads over the fine ones. A coarse thread will accept thicker spirals, making them cut through the forest easier and grab on tightly.
Coating
Costed screws offer protection from moisture which induces rusting and loosening. By and large, the screws that you are using volition exist either coated or plated.
Near all screws are plated with some fabric for protection. In addition to plating, they can as well be coated with an extra layer of zinc for added protection from moisture.
But some are coated with a shiny zinc layer or a golden yellow embrace. A black coat of phosphorus oxide is also sometimes used.
