How to Hide Screws in Wood? Screws are a type of mechanical fastener that has a threaded shaft and is designed to screw into a part.

They are frequently self-threading (also known as self-tapping), which means that the thread goes into the material when the screw is turned. It forms an internal thread that draws the fastened material together and prevents pull-out.

Flooring screws are suitable for a wide range of materials, including softwood, hardwood, and fiberboard.

They’re easy to assemble and are designed to keep boards from splitting. There are a variety of sizes and finishes available for both residential and commercial installations.

Screws rely on thread friction to stay tightly fastened. The radial expansion of the hole in a self-tapping screw accounts for a large portion of the friction.

Friction in machine screws is caused mainly by axial force caused by torque utilised to the head, followed by tension in the screw and part compression. To prevent loosening, machine screws can also use a locking nut or thread-locking adhesive.

         Types of Screw

  • Machine Screw: A machine screw is a type of screw that is used in machining applications, as the name suggests. A stove bolt is one type of machine screw. They’re used to connect heavy-duty metal objects.
  • Wood Screw: A wood screw is probably the most common type of screw. Wood screws are not made of real wood. Rather, they are used to join two or more solid wooden objects. They have a sharp point that can pierce wood, making them ideal for woodworking.
  • Lag Screw: While lag screws are not as common as wood or machine screws, they are worth mentioning. They are essentially jumbo-sized zinc-coated wood screws that are also referred to as lag bolts or coach bolts.
    Lag screws are protected from rust and corrosion by a zinc layer. Companies commonly use electroplating or hot-dip galvanization to apply zinc.
  • Twinfast Screw: Twinfast screws have a unique design that includes two threads rather than just one. They can be driven into objects twice as fast as traditional screws because they have twice the threading.
    Most drywall screws are twin fast screws. Having said that, twin fast screws can be used for more than just drywall installation and hanging.
  • Sheet Metal Screw: Sheet metal screws, as the name implies, are intended to be driven into sheet metal. They can still be used on other materials such as wood, but they are most commonly used on sheet metal.
    Threading extends all the way up to the shank at the top of sheet metal screws, allowing them to easily dig into sheet metal.
  • Security Screw: They are intended to prevent removal or tampering. Security screws, unlike other screws, do not have an operable head that can be reversed to remove the screw.
    Rather, removing them usually necessitates the use of a specialised tool such as a spanner or square driver. Because of this, they are an excellent choice for security applications.

Advantages of Screws

  • The component’s weight is usually reduced.
  • Capability to join high-strength steel with tensile strengths up to Rm = 1500 MPa.
  • The tool must have a small amount of free space.
  • The upkeep of tools is straightforward.
  • With only one nut type t = 0.5 to 5mm, it is possible to join a wide range of sheet metal thicknesses.
  • All types of surface-coated sheet metal panels are viable.
  • In every work direction, installation is simple and easy.

Disadvantages of Screws

  • The components are given extra weight.
  • Bond lines are evident.
  • They necessitate holes, which weaken the components.
  • They bear all of the weight at specific points, which contributes to fatigue.
  • Corrosion and force precision, as well as the difficulty of refastening.

How to Hide Screws in Wood?


Remove any loose wood, flaky paint, or other debris from around the screw hole.

To sand away rough patches, use medium grit sandpaper (less than 100 grit). Remove any remaining residue with a shop vac or a moistened cloth.


Shovel a golf ball-sized amount of filler and a pea-sized amount of hardener onto a hand palette, scrap piece of wood, or other small work surfaces.

Mix them together thoroughly with a putty knife. 2-part fillers come with a small separate container of hardener that you mix with the filler. They are preferred because they dry faster and have a nice, workable texture.

If you’re only hiding a couple of screws, use a smaller amount of filler. Increase the amount no more than a golf ball-sized scoop at a time or you’ll have to work faster to use the entire amount before it hardens. If necessary, prepare smaller batches.


To maximize your control, choose a blade that is no wider than 1.5 inches (3.8 cm).

Fill in the screw and hole with a small amount of filler. Take care not to apply too much filler; instead, spread just enough to make the hole flush with the surface.


When you’ve finished filling in the screws, allow the filler to set according to the manufacturer’s instructions, which is usually 15 to 20 minutes after mixing the filler.

Smooth over your work surface with medium-grit sandpaper (around 100 grit or higher). Remove any residue with a damp cloth or vacuum, and you’re ready to stain or paint.


The filler technique can also be used to conceal screws in metal projects, but a different type of filling material is required.

Use an auto body filler, such as Bondo or USC All Metal, to fill a hole in a wooden project in the same way you would a hole in a wooden project.

Tips and Tricks

  • Make sure the area is dry before applying wood filler if you use a moistened cloth.
  • Screws should be slightly counterbored or screwed just beneath the wood’s surface.
  • Spreading as little filler as possible will facilitate sanding.
  • Wipe the surface with a tack cloth before staining to ensure that all sanding debris has been removed.

They are commonly used to fasten materials such as sheet metal, wood, and plastic. To learn how to hide screws in wood, follow the steps outlined above.

What is the best way to conceal screws in skirting boards?

You can also use a larger drill to countersink the holes in the skirting boards, which will hide the screws and make filling them easier.
Once the holes have been completed (and the plugs have been installed in the wall), simply position the skirting board and secure it to the wall with screws.

What’s the purpose of the white plastic screws?

Plastic anchors protect walls and wall hangings. Plastic wall anchors may be the solution when you need to hang something on a wall but there isn’t a stud in the right place.
They are also known as expansion anchors because they strengthen a screw in the wall surface, making it difficult to rip out.
