Plywood is one of the few wood variations which don’t come naturally. It is in fact an engineered wooden board which is built with multiple layers joined together using glue.
By pressing two or more such layers against each other, this thin board is formed maintaining an impressive strength. For instance, one plywood piece of ¾-inch thickness and measured at 12x36 inches in size can hold up to 50 lbs. with ease.
Its strength is inversely proportional to the thickness. Ironically, the thicker plywood blocks can support lesser weights.
Now you may be tempted to use nails on your plywood projects. While nails are usually the first choice for harder materials, they do not perform so well on plywood because of its softness. Using nails will need you to hammer the bolts into the wood which cause the planks to split up.
That is why screws are the better choice for working on plywood. The best screws for plywood allow you to comfortably drill into the wood without making it split. Besides, the construction and texture of screws are more suitable for driving deep into the blocks.

How To Choose The Right Plywood Screws?
Material
Plywood screws can be made from a number of materials including steel, brass, aluminum and bronze. Usually, most of the screws are made of steel.
It shows the finest performance for both outdoor and indoor woodworking projects. Steel screws also provide strength at an affordable price while also offering a wide range of sizes to choose from.
Comparatively, drywall screws are built from harder material and cheaper than the old-fashioned tapered alternatives. Besides, these screws are mostly self-drilling which makes the work easier. On the other hand, tapered screws are more capable of handling higher stress or drive forces.
Head
The head of a screw plays an important role in any woodworking project since this is what decides how the bolt will look from the outside. Some screw heads can sink flush with the surface while others fail. You can pick your most preferable head from the following popular options:
Bugle Head
Bugle head screws can sink flush with the working surface no matter what material it is. They are usually ¼-inch in diameter and can save your time from pre-drilling holes.
The head portion is a countersunk one where the top is flat and followed by a concave surface. Such structure allows wider distribution of the bearing stress. Typically, bugle heads are used for drywall application.
Trim Head
If your project requires screws which show the least bit of head, then the Trim Head variations are the best plywood screws for you. Similar to the bugle head, this one also automatically sinks flush with the surrounding surface.
Trim head screws provide less holding power than bugle heads and require pre-drilled holes. However, they give better finishing in tasks which need to set door jambs and mountain moldings. These are safe to keep the delicate wood parts from splitting.
Truss Head
These are also called mushroom head screws. The term comes from their structure which has a wider diameter and rounded shape. Truss head is the finest for tasks like mounting hardware where you can achieve good contact between them without making the screw’s presence too prominent on the exterior.
Washer Head
Washer heads appear to be similar to typical round head screws except the tiny washers built into them. Such a design enables the screw to distribute the weight better over a wider space. They are usually self-drilling in nature which don’t require making a hole prior to application.
For a similar structure with wider head, go for super washer heads. These join two plywood planks strongly but also leave room for adjustments. You will find these most prominently in woodworking projects like drawers.
Drive
The drive of a screw dictates how it can be turned. It is basically the arrangement of protrusions and cavities which helps with the creation of torque. While there are many screw drives available in the market, the most prominent and easily available among them are:
Phillips Drive
This is the most common drive observable among the woodworking projects nowadays. They have been popular since the 1930s because of their ability to ensure tight fitting. You can identify it from the cross recess pattern.
Even though their tendency to cam out is not helpful for DIY projects, this drawback is utilized for the better by the automobile factories. It keeps you safe from drilling the screws more tightly than necessary.
Square Drive
As you may have guessed from its name, these drives bear a square-shaped socket on their head. This design makes it easier for you to insert the hardware tool. You can work with it using just one hand, even if the drilling surface is shaking!
Known as Robertson or Scrulox drive, these screws reduce the cam-out effect and thus save you from all the effort of slipping the tool. Besides, you can remove them easily when they get rusty or if they need to be painted over.
Torx Drive
This is another popular drive which prevents cam out. Their socket looks like a star which is why they are also known as star drive.
Similar to the square drives, this one also requires minimum effort from the worker. When you set it on the bit’s tip, you don't need to hold on to it for driving anymore. So you can operate the Torx drive screws with just one hand.
Thread
The thread refers to spiral encompassing a screw. Its presence enables the screw to be self-drilling. Usually, the coarse threads are better for plywood than fine threads since they establish stronger hold in it.
However, nowadays they both are doing well because of newer designs of fine thread being incorporated into screws. Along with plywood, these threads have proved to be effective in many other materials.
Point
Driving any screw begins from its end point or tip. It is responsible for creating the opening effortlessly into the plywood plank and driving the rest of the screw into the block.
The most common point you will see in screws is the Type 17 which is used in construction, production and deck jobs. It has the maximum sharpness that easily penetrates materials even harder than plywood.
Coating
Screws made of steel are generally coated or plated with another material to ensure high durability. The difference between these two processes is that plating is always applied to bare screws while coating may be done to bare or plated screws.
Steel is prone to forming rust or corrosion especially when in contact with moisture. Coating or plating with zinc stops that from happening to some extent. Another transparent or colored chromate layer of coating on this zinc can prevent white rust from forming.
You can also go for screws with black phosphorus or black oxide which provide the steel screws with mild security from corrosion. Along with protection, coating also gives screws enhanced appearance of more appealing shades like golden, black, silver etc.

Benefits Of Using Plywood Screws
It may have crossed many of your minds - why not just use nails for these woods? The main reason is that applying nails on softer materials like plywood cause the planks to split. So for any woodworking project, screws are the superior choice almost every time.
There are also a number of other benefits to choose plywood screws. The most prominent ones among them are:
Generates Torque
Screws which are meant for woodworking generally come with fine threading which are able to create the necessary amount of torque. These threads are meant to drive deep inside the wood blocks.
The torque is created because of the way they bite into the planks. This force helps to keep the two planks or blocks of wood to join together properly. Such threading pulls the blocks well regardless of any existing gap or warp between them.
A trick to make this connection even stronger is to apply some glue to the individual wood blocks before using the screws on them. Doing so can make their bond permanent where the screw will function like a clamp.
They Can Be Removed Easily
If there is ever any need of replacing the screws or simply getting rid of them, you can do so easily with these wood screws. As a result, you don’t have to worry about making a mistake here and there in your project. If there is one, you can just remove the mistaken screw and replace it with the right one.
You can also get rid of any such bolt for good. This applies to any furniture, deck or similar piece created with screws.
Convenient Use
These are very easy to use because of their structure. No matter what kind of screw it is, there will surely be a sharp tip at its end to penetrate the wood block easily. Then comes the threaded part which takes off a considerable amount of effort from the user and makes its own space inside the plank comfortably.
Finally, the head drive puts the “nail in the coffin” by ensuring the fit is tight enough. Certain drives like square prevents cam out so that you can maintain an impressive speed with the project.
So from the beginning to the end, the wood screws continuously make the process easier to get by for you. By investing in a self-driving screw, you will not even need to exert the pressure for drilling the hole.
Affordable
People might think that the best screws for plywood usually come with a hefty price tag. That’s not true. Plywood screws come at a very affordable price point. You can get a hundred of them in less than ten bucks or over a thousand of them within less than fifty.
Moreover, compared to nails, you need less screws to cover a certain area and achieve the same reliability. The variety of sizes available here also helps with your purchasing decision and productivity. You can use the same screw on a wide range of surfaces as well.
Strong
Wood screws tend to be stronger than nails. They are not prone to bending, breaking or shearing off regardless of the heavy wind, traffic or weight. You don’t have to worry about them falling off either since screws don’t get loose like nails. Even if a screw does seem ill-fitted, you can push it back in with minimum effort.
Because of their high tensile strength, screws are able to provide a superior performance at an economical cost.
Frequently Asked Questions:
What Thickness Of Plywood Are Usually Available To Use Screws?
Answer: You can find plywood sheets in various sizes with thickness from ⅛ inch, ¼ inch, ⅜ inch, ½ inch, ⅝ inch, ¾ inch, 1-⅛ inches and 1-¼ inches. Among them, the thickness of ⅜ inch and ½ inch are the most easily available options. The largest plywood blocks can be up to 3 inches in thickness.
Do You Screw Or Nail Plywood?
Answer: It is better to use screws on plywood instead of nails. Screws are more suitable for the soft plywood blocks since they can be removed more easily and do not cause splintering. You don’t have to worry about splitting the wood by using screws.
Can You Use Drywall Screws For Plywood?
Answer: While drywall screws have their own share of advantages for many materials, it is better to use wood screws for softer elements like plywood. The drywall screws consist of harder steel which are more likely to split up the plywood planks.
Can You Screw Into Plywood End Grain?
Answer: Yes, you can screw into plywood end grain but we would not recommend it. For that you will need to drill into the dowel and glue it. Another way to do it is giving the plywood a cross-grained wood or hardwood plug for biting into. This will ensure stronger hold.
Can I Use Sheet Metal Screws In Plywood?
Answer: Sheet metal screws are ideally used to join metal sheets. So they may not be the best solution for joining plywood blocks. However, if you don’t have any wood screw at hand, the sheet metal screws can be used for plywood projects. They may not perform as well as wood screws but will get the job done.
Are Square Drives Better Or Phillips Drive?
Answer: They both have an advantage over the other. Phillips drive are prone to cam out but ensure tight fitting without overdoing it. This is why factories and automobiles rely on it. In contrast, square drives prevent cam outs by establishing a strong grip and enabling better self-drilling capabilities.
If you are unsure which one to go for, you can settle for the hybrid drives which support both Phillips and square variations.
Final Words
The best screws for plywood largely vary according to your individual project requirements. You will need to count in many factors starting from the thickness of wood blocks to surrounding environment of the end product.
Exposure to moisture will play a huge role in this decision since not all screws are built to survive the wet areas. Some are more prone to forming rust than others which can harm the whole structure in the end.
Besides, you may have functional and aesthetic preferences as a carpenter. There are many drives and heads to choose from among these screws. Each of them comes with their own set of benefits and drawbacks. Some will prevent cam-outs while others will ensure reliable long-lasting fittings.
There is no shortage of size variations for these screws. So you can find the most suitable one for your task quite conveniently from such an abundance of options.
