Wood Screws vs. Deck Screws: What’s The Differences?

There are many types of screws and chances are, you may not know the difference. Screws come in different shapes and sizes and each is meant to serve a specific purpose. Shockingly, even deck screws are quite different from the ordinary wood screws. If you are decking, then you should consider using decking screws as they will be far much better than nails or wood screws.

As a layman, I understand that you can easily be confused about the screws and may end up using the wrong type of screws. Wood screws will serve you perfectly when you are joining cabinet, furniture parts as well as mounting hardware and so much more. Unlike nails, screws will form a stronger bond between the surfaces that you are joining and they reduce the stress on the joining point.

When you take the time to compare the deck screws and wood screws, you will notice the glaring difference. Their heads, coatings, plating and even threads are quite different. Stay with me and I will educate you on the differences. At the end of this article, you should be able to differentiate between wood screws and deck screws. Let’s get to look at these differences.

What are Wood Screws?

A wood screw is a general term that is used to describe a metal screw with a sharp point and a flat head. This is used to attach pieces of wood together and they come in different shapes and sizes. There are wood screws that have pan, flat or oval heads and the shank below the head is unthreaded.

Wood screws are used for mechanical fastening in woodworking. They serve as a perfect clamping force and will connect wood to wood, providing a strong joint. Wood screws can also be used to attach locks, hinges and other objects.

What are Deck Screws?

Deck screws are similar to the wood screws, and you will easily confuse the two. The biggest difference is the fact that they have a larger surface area. This will give you a greater capacity to bear load. Decking screws are made of coated steel or copper, which makes them corrosion-resistant. This makes them ideal for decking as they can withstand all manner of weather conditions.

You can use the decking screws for soft and hard wood applications. In general, they are similar to the wood screws, but a closer look will show you the difference. These are longer and come with sharper tips than the ordinary wood screws.

Differences between Wood and Deck Screws 

When you look at the basic design, both screws appear to be the same. Before going out to shop for the specific type of screws, here are some differences that you need to be aware of:

Heads

The head of the deck screw is the same as that of the wood screw, as they both have a flat head. However, you will notice that the head of the deck screw has a bigger surface area. This is what makes it a safer option as it carries more capacity to bear load. The heads of deck screws also have a flare or bugle shape, which is not the case with wooden screws. This prevents the deck screw from sinking into the material and as such there would be hardly be splitting or cracking. This is not the case with wooden screws as they can go all the way in.

Threading

When you look at the wood screw, the threading is not tapered and also very sharp. This affects their efficiency in the long term. Deck screws, on the other hand, have very deep and sharp threading. This makes it easier for you to cut into the wood boards and secure the pieces together. If you are looking for efficiency and effortless bonding, deck screws will be the ideal choice.

Shank 

The shanks on deck screws are also designed for longevity. They come with sharp and a tapered threading, with and an aggressive tip. This allows you to screw them into the surfaces fast and easy. This secures the pieces of wood that are being joined, with no room for movement. Wood screws, on the other hand, have a similar shank, but the threading is not as deep. The shank is not fully threaded and you have some challenges taking the screw all the way into the wood.

Construction Material 

Most screws are made of steel and this will not withstand all weather conditions. After a while, you will notice that the screws will start to rust, especially in wet environments. As for the deck screws, these are made of coated steel or copper, which is resistant to corrosion.  This makes the deck screws suitable for different applications as they will never rust.

Conclusion

There you have it, now you can tell the difference between deck screws and wood screws. The basic design may seem to be the same, but as I have shown you, there are certain elements and features that are different. When shopping for screws, it is imperative to ensure that you are going for the right type.
