What are deck screws?

Deck screws have similarities as that to wood screws in terms of appearance and design. These have a larger surface that can adapt to varying workloads.

These are usually corrosion resistant and withstand varying weather conditions because of their usual coated steel or copper material.

What are the differences between deck screws and wood screws?

The differences between the two are that deck screws have sharper and deep threading and have more bearing power than their wood counterparts.

Bearing power, also known as holding power or ground adherence, refers to how firm a screw can hold lumber or deck plants together.

A higher holding power means greater tensile strength; thus, deck screws are better than wood screws in this area.

The basic types of deck screws

Using the appropriate type of deck screw is essential for you to effectively manage your work. Choosing the wrong one will give you disastrous and often visually-unappealing results.

Screws have varying construction and composition depending on its use. You may choose by type or structure, depending on your needs and preferences.

Here are some of the types and structures of deck screws you should be familiar with and when to use them:

Decking or framing screws

Deck screws deliver a powerful performance for a variety of construction work.    

Reversely-threaded

Before purchasing this kind of screw, you must know first how to use it and how it accomplishes the task, as this type is highly dependent on the user.

Wood screws

This kind of screw falls within the average price and is reliable and durable. From the name itself, it is best for wood, framing, or decking works.

Drawback
  • Does not offer longevity.
  • Pushing it hard may leave scarring or mark on the wood.
  • The tendency for the plank to rot because of water sipping in.

Composite deck board screws

This has a better construction quality and is a top-notch quality fit for great performance. Issues such as mushrooming and high-torque tolerance are resolved.

Adjustments in the threading zones back were also made.

Choosing screws by structure

Rugged structure

Screws with this structure have tighter threading and sharper tips. Its structure makes it self-driven and convenient to use.

Its durability relies on its manufacturer, and it usually comes from various manufacturers.

Head type

Screws have varying head types such as round, flat, cap, and trim. However, among these choices, the flathead works best for decking.

Flathead

Because of its durability, reliability, and good construction, it is the best choice for projects which require shear resistance, such as structural parts and poles.

It can easily be spotted with its star head drive.  Usually, flat head screws are also self-countersinking. It means that its head will automatically level with the deck ground so the surface’s texture will not be distorted.

Assorted collections

  This can perform a variety of projects, but because of its build and capabilities, its durability will still depend on the brand manufacturer.

Deck screws for pressure-treated wood: buyer’s guide

Before buying deck screws, it is important to consider the features and capabilities to not have a regretful purchase. We compiled a list of things you should consider when choosing a deck screw.

Purpose and usability

Once you know what and where you will use the screw, your choices will get narrowed down and you won’t be overwhelmed by the number of choices.

Determine first whether you are using it for carpentry, DIY projects, heavy industrial works, or small to medium scale projects.

For simple DIY projects, you may opt for inexpensive ones instead of renowned brands with flat-heads or Phillip heads. If you want convenience and fewer stripping issues, you may choose Robertsons heads.

It is important to choose a screw that will give you a convenient and hassle-free experience. If you are an amateur, choosing a multiple-purpose screw is your best shot.

Aesthetics

Choosing screws that match your expensive pressure treated wood planks will ensure that you will get a seamless, aesthetic-looking deck. This is an important consideration as not to ruin your deck’s appearance with those distracting little screws.

Construction

In the construction of the screw, there are several considerations, such as the material, coating, and threading.

Material and weather resistance.

Screws are usually made with steel or stainless steel. Screws made of steel can be more fragile than the stainless ones. The latter is the ideal option for outdoor installation such as decking.

If you want the extra benefit of weather and corrosion- resistance, opt for 304, 305, 306, 18-8, and other high-grade stainless steel. Doing so will give you security and longevity even when dealing with harsh weather conditions.

Electroplated screws also last longer than normal ones.

Bottomline: A steel material is strong and durable and prevents wood splitting due to its no split shank design. It has a great coating capacity for keeping a compact and firm deck.

Coating

For pressure-treated lumber, avoid galvanized coating as it can easily be damaged. Choosing a stainless-steel finish with a ceramic coating is a good option, however, it can be more expensive.

You may also opt for other top-notch, high-quality brands. If you are not a professional, choosing top brands is a good call as most of their screws underwent metal treatment.

You may also ask the advice of a builder or carpenter for their brand and product recommendations.

Bottomline: A deck screw for pressure-treated wood is perfect for outdoor applications as it is rust and corrosion-resistant.

Drive type, thread and tip

For ease of installation, choosing the right drive type is vital. Some proven and tested drives are square, Torx, and Philip drive.

You must also choose a thread to ensure a strong and long-lasting hold on the wood, such as serrated or coarse ones. Lastly, choose a screw with a tip that won’t need pre-drilling while being able to effortlessly hold into the wood.

Bottomline: Deck screws have sharp screw points that make it easier for them to dive into the wood. Some also have drives that eliminate cam-out, and no longer require pre-drilling.

Bit and size

Deck screws size range between 1.6 to 3.2 or 40 to 80 mm. This figure is ideal for construction work. Different tasks require varying sizes and drill bits in diameters.

Bottomline: There is no standard size, length, gauge, and drill bit for screwdrivers because it depends on what task you are planning to accomplish with it.

Reminders when using deck screws

Deck screws, even if small, can cause injuries when not used and handled properly. Here are some safety precautions to abide with:

  • Use protective gear when handling power tools and deck screws
  • Be aware of how much torque your screws can handle to avoid chips and cracks
  • Properly drive the screws.
  • Be mindful of damages caused by head stripping.
  • Screw threads are vital because pulling out shallow threading can be a challenging task.

FAQs

We compiled the most commonly asked questions to help you know more about screws.

What are the different deck screw types?

One consideration in classifying deck screws is the material it is constructed with. Some use polymer wood, stainless steel, etc.

These differences in construction and composition account for its usage. Deck screws are ideal for heavy needs such as construction work.

What are the differences between a self-tapping versus self-drilling screw?

Self-tapping screws are advantageous because they produce less debris and dust and provide more torque and driving power. The only drawback is that it needs pre-drilling holes before usage.

On the other hand, self-drilling screws no longer need pre-drilling holes before usage, as these are constructed to create a drilling hole in the process.

Are treated lumber and pressure treated wood the same?

Treated lumber and pressure treated wood are two terminologies used interchangeably in the industry because of the few differences. Treated lumber involves using a technology to upgrade or treat a certain kind of wood, thus its name.

However, pressure-treated wood underwent pressure treatment through a vacuum chamber to empty the wood planks. This also uses preservatives in it.

Thus, pressure-treated wood planks have better resistance against dampening and infestation.

What is meant by a deck screw’s “holding power”?

A deck screw’s holding power means how well the screw can hold or connect different lumbers. It is also known as ground adherence.

Ground adherence means greater tensile strength, which can lead to the better internal structural integrity of a deck.

What is meant by a “self countersinking deck screw”?

This kind of deck screw, the self-countersinking, is named after its countersinking nibs. It has a flat head that levels at the deck ground.

This feature makes it camouflage well from the surface and not distort its appearance and texture.

What is the best deck screw size for regular work?

For regular work, you may use the average deck screw size, about 1.6 to 3.2, roughly around 40 to 80 in length. Different tasks require different screw gauges, lengths, and sizes.

Is there a standard bit for deck screws?

No, there is no standard bet for deck screws. Deck screws with varying sizes need the different diameters of the drill bit.

The driving style is to be considered as well.
