Differences Between Wood and Deck Screws: Are Deck Screws Strong

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:


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 the 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.


When you look at the wood screw, the threading is not tapered and is 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.(Best Deck Screws)


The shanks-on deck screws are also designed for longevity. They come with sharp and tapered threading, with and an aggressive tip. This allows you to screw them into the surfaces fast with ease. 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.

Can I use standard wood screws for decking?

No, wooden screws are more eligible for joining parts rather than fastening. That is to say, you cannot make them used for decking, just like you do in the case of deck screws.

Standard wood screws tend to become weak, split, and decay at the fastening point. As a result, there always remains the risk of damaging your component when you use such kinds of screws for decking purposes.

Therefore, the structure of these wooden screws is not suited to fit the task of fastening or decking.

In addition, deck screws use copper or stainless steel as the primary raw material for their manufacturing. These components are way more vital than most of the other materials like iron, steel, etc.
