Best Wood Screws – Buyer’s Guide
Back in the 90s, you could only buy one of two screws, Phillips or slotted. You only needed to pick one, choose the length, and that was all. Since then, the fastener market has grown exponentially.
For a DIYer, you are offered a wide range of solutions to get your project done. Back in the day, the screwdriver was the only means of driving screws and the Philips was the most popular screw.
But today, there are other tools including cordless drivers and lithium-ion drivers, which reduce slippage and stripping.
Which Screws are Right for your project?
With the wide range of screws, it is challenging for Do-It-Yourselfers to choose the right screw. The screws are offered in different lengths, materials, head types and coatings.
Choosing a good quality screw makes the difference between a good project and a poorly fixed woodworking project.
With the sea of screws in the market, it is easy to get confused. As a beginner, you will wonder which screw length and width to choose, which coating and which material. Screws are undoubtedly versatile, but choosing the right one is not easy.
Where do you need screws?
If you need to quickly build jigs, join cabinet and furniture parts, mount hardware and trim among other projects, you will need screws.
With a good screw, you will form a strong connection between solid wood and plywood without the need for joinery cuts.
You can also use screws to reinforce parts that have been assembled with conventional joinery for instance pinning tenons in mortises.
While a few decades ago you only needed to choose between zinc and brass screws and the right size for the job, there are a host of choices today.
Understanding Wood Screw Types and Materials
Traditional wood screws were made from comparatively weak steel. Ergo, their slot recesses would deform or come out. When driven with ambitious force, their shanks would snap. But, like you might have realized, modern screws are relatively strong.
Screws are made of brass, bronze, aluminum or steel. Among these materials, steel screws are the best for interior DIY projects and for professional woodworking. These screws are strong, durable and available in different sizes.
Most woodworkers started using drywall screws when they become available. These screws are strong and do not need predrilled pilot holes.
However, they are relatively brittle and might snap when high force is used to drive them, or if they are exposed to high stress. They are, therefore, not ideal for projects requiring strong construction.
Production screws have replaced traditional tapered screws. These screws pack sharp and strong threads and tips, allowing them to penetrate even the hardest wood.
These screws can be used to penetrate other manmade materials. The heads and shanks of these screws are designed strong to withstand high torque.
Most hardened steel screws are often sold as multipurpose or construction screws.
There are different grades of steel each for a different project.
Choosing a Head Type
Irrespective of the screw material, the shape of the screw head has a great impact on how the screw works. Screw heads can be categorized into those that sink flush with the work surface and those that do not.
Trim head and bulge head screws sink flush with hardwood and delicate wood. When used on pre-drilled holes, the screws are better than finish nails when setting door jambs.
Flat and oval head screws are the most traditional screw head types. They make projects look nice. Most flat head production screws are self-countersinking, allowing them to create their own recess and sit flush with the wood surface.
The traditional round head screw, pan head and cheese head screws sit proud of the wood surface. These are designed with a small head and a flat bottom that bears against the work surface.
While this offers a significant amount of hold on the surface of hardwoods, the small head might tear the surface of softwood. When fastened pieces are exposed to stress, the hold of these screws is reduced.
A screw with a large head offers a large contact area and, thereby, offering great resistance to pull-through and penetration.
Unless you are creating period-style furniture, you will not choose a traditional tapered wood screw. Why? These screws tend to slip off when you are driving them in. However, you can still use Phillips head screws.
Today, Torx star drives and Robertson square drives are among the most popular. Star and square drives are easy to drive with a manual screwdriver or a cordless driver.
Stick fit and cam-out resistance make Star and square drives ideal for use in many woodworking projects. Stick fit is the quality of screws to stick to the bit, ensuring that you do not have to hold them when driving them in.
The two heads above feature deep recesses where the bits fits snugly. This reduces chances of cam-out and also protects the driver from wear and damage.
Pozisquare and Outlaw drives are also popular on many screws. Pozisquare is a hybrid of #2 square drive and #2 Philips. When used with Pozisquare bits, you will experience great stick fit and cam-out resistance. Outlaw drives feature a hexagonal head recess offering super stick fit and high cam-out resistance.
Covering Screw Heads
If you need your screws to have a decorative detail on your project, you can use screw head covers. Do you need shiny brass screws on the edge of your cabinet or jewelry box? Or do you need the screws not to show on the surface of wood?
Covering the screw heads is one way of achieving a good finish on the surface of wood. The best way to make flat head screws disappear is to set them on counterbored holes and then top the holes with flush-trimmed wood plugs that match the surface of the wood.
During a project, you can drill pilot holes and counterbores separately and then choose a bit that offers both functions when driving the screws.
If you need a good appearance instead of hidden screws, you can choose decorative domed, button plugs or screw covers. There are varieties of these in the market. Wood plugs glue into counterbored holes, keeping the screws hidden and offering a great look. These decorative covers come in different shapes, sizes and finishing; your preferences will determine the head cover you choose.
The covers may be made of anodized aluminum or plastic among other materials.
Screw Points and Threads
You want a screw that you will drive smoothly, right? You, therefore, need to consider the threads and point of the screw you buy. The threads and the point should pierce the wood and pull the screw in while ensuring that the wood does not split. Once driven in, the threads must ensure that the joined parts do not separate even when exposed to stress. When the threads are shallow, they do not offer enough holding power to keep the joined pieces together.
When the point is dull, driving the screw will not be smooth.
Deck, production and construction screws are designed with sharp points and threads. The threads are larger in diameter than the screw’s shank. This allows them to penetrate hardwood and other materials without you having to unnecessarily drill pilot holes. This, in turn, saves time during installation.
A good screw point should bite into the wood surface and pull the screw down, creating a hole for the shank and the threads. Most of the modern screws use Type-17 Auger point to deliver great performance.
This is a needle-sharp point designed to penetrate even the hardest material. But you need to be careful when handling this type of a screw as it might equally penetrate your fingers.
Most screws feature a self-channeling flute that cuts a hole on the surface of wood and throws debris upwards. This pulls the screw smoothly and reduces outward pressure that might cause splitting.
After the tip has created a hole and pulled the wood screw down, it is the work of the threads to drive the point the rest of the way down. Conventionally, fine threads are used on hardwood while coarse threads are used on softwood. However, newer thread designs have allowed screws to be used in a variety of applications.
Threads such as cross-cut, QuickCutter and lead spiral threads are designed to reduce the torque needed to drive them through wood. In some designs, screws feature knurled shoulder thread just above the normal threads. This allows the screw shank to turn with ease. This also increases the clamping force between the two pieces to be joined.
Screw Plating and Coatings
Plating and coating are the last steps in the production of steel wood screws. Plating is done on bare metal screws while coating can be done on bare metal or plated screws. Screws are plated or coated to prevent corrosion, enhance appearance, and reduce friction.
When not coated, steel screws rust within a few days of exposure to moisture. This is what plating reduces. Bright zinc is the most common plating material on wood steel screws. The zinc is more of a decorative finish, but still offers corrosion resistance.
Bright zinc plated screws are susceptible to dull white corrosion unless a clear coat is added. Golden yellow zinc, on the other hand, is better for corrosion resistance and has been used widely on construction screws.
Black oxide plating reduces rusting, but offers little to no protection against corrosion. Most modern screws feature high-tech coatings for outdoor environments.
You can choose between different screw colors, including black, tan or white, to match the color of wood. The feature comes in handy when hiding screws.
When the surface lubricity of a screw has been increased, it becomes easier to drive these screws. Slippery screws do not cam-out with ease. During use, you can lubricate the screws using beeswax or candle.
However, it is easier to buy screws that are already covered with a lubricating coat. When that happens, the screws will have no residue and will drill with ease.
Length is an important aspect of wood screws. The rule of thumb is to choose a screw that enters half the bottom wood’s thickness. Screw diameter, or gauge, also matters a great deal.
Screws are offered in gauges 2 through 16. #8 is the most versatile screw gauge. For fine wood, #6 is the best. For heavy and hard wood, #12-#14 will get the job done.
While wood screws may look simple, your choice of screws will make or break your project. The quality of a screw will determine its price and durability. There are different brands and models and the one you choose is a matter of preference; this is after you have considered other factors such as length, gauge, threads and coatings.
Even when the quality of a screw looks great on paper, it is advisable to consider user reviews. This will tell you how durable a screw is and its resistance to elements. Ensure that you choose a sturdy and durable screw.
