Types of Wood Screws and Uses
There are many wood screws on the market today. I wanted to provide you the best types for you to give the best woodworking experience. When you are looking at the many options they have common features. Here I will go over the basic features of the wood screw and what you should be looking for.
Nails And Woodworking – Misconception
Before we dive into the realm of wood screws I wanted to clear up a misconception I see on forums and discussions boards regarding nails and woodworking. Many woodworkers are seen and teach using nails in their woodworking projects. For folks who don’t commonly do woodworking on a regular basis, nails are considered to be the norm and not wood screws.
Contrary to what you may think screws are used more than nails. Don’t get me wrong nails such as brad nails for example are great for securing woodworking projects while the glue is drying. Or for smaller wood projects or for simply to hold woodworking projects together in preparation for final assembly. However, wood screws are a much better solution for securing your wood projects and will provide greater longevity for your woodworking projects.
Parts or Anatomy Of A Wood Screw
To truly understand a wood screw I wanted to provide the best description of the wood screw and each of its parts. As we continue further in our charts below and more detailed information this will benefit you.
A screw is made up of 4 components:
TIP – Wood screws that are used in woodworking have a pointed tip that assists the screw into a precise location. These self-drilling wood screws and cut into the wood like a drill bit.
Shank – The shank is the part of the wood screw right below the head and does not have threads. The importance of this is the ability of the screw to draw the wood material together.
Threads – The threads of a wood screw are the key to its success in keeping your wood projects together and tight. Wood screw threads are wider and more aggressive than metal threads and are the key to them working so well.
Head – The head of the wood screw is the most confusing for most beginner woodworkers with so many different types of heads which require different types of tools to use them.
Here is a great video which describes wood screws
With time the wood screw head type has changed. In the past it was ahead that required a flat head screwdriver, then migrated to the Philips’s head, and to the Torx. You may ask yourself which is the best.
The best type of wood screw head is a personal choice. The latest type of screw head is the star Torx. This type of wood screw head would require you to purchase a Torx attachment for your drill or Torx hand tool set.

Countersinking your wood screws is preferred for the best holding ability of the wood screw as well is preferred from an appearance perspective. Below I wanted to include a good reference for your to consider when using the wood screw sizes along with the countersink size appropriate for each wood screw size.
|Screw Size||Countersink Size|
Wood Screw Length
How do you determine the wood screw length for your wood projects? There is no real science to determine this for you. However, you can take a common-sense look to help you determine. A general rule is the wood screw needs to go through the thinner piece and then thread into the thicker piece of material.
Using this general rule you would want to have 2/3’s of the wood screw in the thicker piece of wood material. Also, as the material you are initially placing the wood screw into thickens, you may want to only have 1/2 of the thickness of the wood screw in the bottom material.
Wood screws are the secret to woodworking project success. Choosing the appropriate wood screw will save you time, effort, and frustration. The most common choice of most woodworkers is the #8 screw at 1 1/4 long and will serve you well. Have plenty of them in your wood shop and you will never go wrong.
