screw in wood

Do you ever feel like your screw isn’t doing its job? You put it in, twist, and wring the handle of your drill, but nothing happens.

It’s not unexpected to get frustrated – we all want our projects finished as quickly as possible – but if you’re facing a situation where a screw won’t screw in wood, there is likely something else at play. Let’s explore why this is happening and how you can fix it so that your project can be back on track!

*This post is about why your screw will not screw in wood

Basics Of Wood Screws

When driving a screw into wood, the screw needs to be able to penetrate the grain of the wood and create a stronger hold. This is because when screwing into any type of material, you are forcing the screw’s threads through that material. If the screw is too big, it won’t fit properly and will not be able to penetrate.

On the other hand, if it is too small it won’t be able to generate enough torque to penetrate.

Wood screw types come in several different sizes and are designed for specific applications. It’s important that you choose the screw type and size that works best for your project.

If you use a screw with threads that are too coarse for the material, it will not fit properly and will be unable to penetrate.

Wood Screws And Wood Screw Sizes

Generally found with DIY wood screws and reassembling wood parts. If you want good screws to use for woodwork, sharp models with wedge-shaped shanks are needed.

Wood screws have a semi-threaded shank which can be ordered in different length sizes and drives. Number 8 screw heads are standard and are used on most woodworking jobs.

Choose a screw of a width that penetrates half that of the top when fixing wood.

A good option for a standard wood screw is Hillman #8x 1-1/2 inches. Silver zinc-coated wood screws. It’s the right size to join 1x2s and works well for interior building projects.

Deck Screws

Deck screws are typically constructed with stainless steel that withstands corrosion when used on outdoor surfaces. It can be used to build outdoor furniture, garden furniture & window boxes as well.

Find the screws with stars in them so they are less likely to be removed. This is done because these machines are very efficient at transmitting the maximum force of a drill. Deckmate star flathead screws are suitable to fit on standard decking if required.

It features star drives and corrosion-resistant finishing. All 1 lb boxes contain stardust drill bits.

Pocket Hole Screws

The pocket hole screws connect the wood to the pocket through predrilled holes. Pocket holes are often used in cabinet building for their ability to hide from view.

When used in pocket hole jigs these are the best way for joining materials. The screw tip has a self-drilling tip so it does not require drilling a pilot hole before gluing two different material components.

The drill bit used with the power drill typically has a rectangular inset on the screw head. Using this drill bit it easily fits into any drill bits or screwdriver and eliminates a stripping screw scenario, even for quick spins.

Anatomy of a Screw

Let’s start with the basic screws feature so you can make a better decision about the product. Drive: The shape of the screw insertion or removal device.

Typical drives are hex-shaped cross-heads, square star-shaped, and slotted.

Head Of The Screw: The top screw that encloses the drive.

Shank: Smooth area with a fastener between the head and thread. Various types of screws are available, and some have rough sizing.

Thread: The groove that wraps around the cylindrical shape into helixes.

Shank of a Wood Screw

The shank is positioned inside the screw. If we imagine a screw that has no thread, it has a shank, like a nail. The shanks serve as the foundation for the screw and perform several roles.

If you are drilling into holes you need to check if your drill is right in diameter – not threads! Then the surrounding wood can stay in the ground until the thread can grasp it and give the appropriate grip.

Tip of the Wood Screw

The screw’s tips puncture the surface allowing it to be driven into the wood. Several wood screws may have this name on their side if they are pressed into the wood and pushed in the screw.

Some screws are blunter – they are best used to create a pre-drilled pilot hole, especially in hardwood.

Threads of a Wood Screw

The thread is spiraled onto the screws. Often the angled threads have different sizes and are used in wood types.

Head of a Wood Screw

The screw in the head twists the screw onto a piece of wood to create a screw. It consists of three categories that serve different needs.

Choosing the right type of screw

All the screw components are made of the material intended for use. Although drywall screws work well, it’s not always the right option.

The choice of the correct screw can have several advantages. Some materials are ideal for decoration, and some are durable for outdoor construction.

Working with Dense Wood

If you determine the problem of not being able to drill a screw into the wood is not the drill, there is an obvious possibility that you are only working with hardwood that has a particular density that makes the screws hard to penetrate.

Fortunately, there are many ways to make securing screws into the wood easier such as using a drill bit to create a pilot hole.

Creating a pilot hole typically resolves this issue. A pilot hole is a hole drilled prior to driving screws into the wood and the pilot hole is typically smaller than the size of the screw itself.

Most woodworkers drill pilot holes every time they utilize screws.

Screw Driving Basics

Let us see if you know what’s wrong with your drill and your tool and what’s going right with it!

A screwdriver should not be too weak, so the screw is unable to penetrate the material.

Also, you need to make sure that your drill bit is in good shape and its edges are sharp enough to drive screws into wood.

Tips To Help You Drive A Screw Into Wood

Now that you understand the basics of wood screw types and sizes, let’s look at some tips to help you drive screws into wood:

– Pre-Drill Holes (Pilot Hole): If the screw isn’t penetrating the wood, pre-drilling (With a drill Bit) holes (Pilot Hole) can help. This will allow the screw to get a better grip on the material and penetrate more easily.

– Use Screw Lubricant: Using screw lubricants, such as wax or oil, can also help the screw go in easier.

– Select The Right Screw Type And Size: It’s important that you choose the screw type and size that is suitable for your project.

– Use A Drill With A Screwdriver Bit: Using an electric drill or cordless drill with a screwdriver bit will help ensure that the screw is securely fastened in place. This can also create more torque, allowing the screw to go deeper into the wood.


Should The Screw Head Be Below The Wood Surface

The screw head should not be below the surface of the wood. If it is, this could cause the screw to loosen over time. Instead, make sure that the screw head is flush with the surface of the wood.

Can I Use Any Screw With Wood Projects

No, you should take the type and size of the screw into consideration when selecting a screw for your wood projects. Make sure that the screw is suited for the particular material it will be used on.

What Is The Best Way To Drill Screws Into Wood?

The best way to drill screws into wood is to pre-drill a pilot hole (with a drill bit) and then use the screwdriver to screw it into the wood. This will help ensure that the screw is secure and that it penetrates all of the ways into the material. Additionally, using a power drill with a screwdriver bit can increase torque and make driving screws faster and easier.

Does The Length Of A Wood Screw Matter

Yes, the length of a screw is important to consider when working with wood. If a screw is too long, it might not penetrate all the way into the material and can lead to splitting or other issues.

On the other hand, if a screw is too short, it won’t securely hold in place as you want a firm grip. It’s best to measure twice and select the screw that is correct for the project.

What If I Have A Stripped Screw Hole

If you have a stripped screw hole, the best way to repair it is to use a screw extractor. This tool can help remove screws that are stuck or stripped. Once the screw has been removed, you can fill the hole with wood filler and let it dry before drilling a new pilot hole and using a screw of the correct length.


By understanding screw types and sizes, pre-drilling holes, and using screw lubricants and screwdriver bits, you will be able to drive screws into wood with ease. Paying attention to these details can save you time and effort so that you can get your project completed faster!
