Factors to Consider when Buying Deck Screws for Pressure Treated Wood

Being able to make an informed choice while buying screws for your pressure treated wood deck is a step in the right direction towards ensuring the durability of your decking. Though it is not really a cause for concern, it helps a bit to know the preservatives used in treating woods for decking.

With that out of the way, let us take a look at some of the most important factors to consider.

1. Screw Type

Best Deck Screw for Pressure Treated Wood in use

Each new year sees the advent of new types of screws in the market, each promising to help you achieve one thing or the other. It takes some level of experience to be able to differentiate one screw type from the other appropriately. As a matter of fact, there is a lot to learn about screws suitable for wood decking.

Screw types are differentiated into different categories based on their tips, coating, and recesses. Across these categories, some of the identifying features help determine their suitability for wood decking projects. The features for each category as listed below.

  Screw tips:

  • Auger tip
  • Serrated tip
  • Fluted tip

Recesses:

  • Phillips drive
  • Phillips/square drive
  • Square drive
  • Torx (star) drive

Coating:

  • Stainless steel
  • Silicone bronze
  • Steal coatings (up to six types)

2.  Area of Usage

Are you constructing a wood deck for interior or exterior use? Is the board hard or medium? Is it thick or thin? Is it for a trailer floorboard? Which part of the deck do you need the screws for – the ledger, connectors, framing, joist, blocking, or deck boards?

Just as various parts and components of your electrical appliances are fastened using different screws or nuts, so are various parts of your decking fastened with different types of screws. Bear this in mind when buying screws and ask for recommendations, and you can be sure of avoiding various technical issues while working.

3.  Screw Quality

Sure enough, you will see lots of screws with all the bells and whistles promising unfailing perfection. But really, how are you sure that the screw you are getting is of top quality? For decking, the best quality screws are mostly, if not always, screws made of stainless steel.

You should note that while this does not negate the quality of other screw types, it does not assure the quality of stainless steel screws as absolute. However, it is certain that screws that have positive results after being test-rated for a minimum of 1,000 hours are more likely to be of good quality than those that weren’t.

Also, check to know if the screws in question are code compliant. Fasteners certified within relevant industry codes are likely to be of good quality, assuming that they have undergone some industry-specific tests before being awarded the compliance.

4.  Corrosion-Resistant Feature

There is no definitive determinant that slams the gavel on corrosion resistance qualities of screws. Some screws might do better in some types of pressure treated wood than they would in others. When buying woods for your deck, the trick is to ask the seller if there are recommended screws and fasteners for that particular wood.

For example, a lot of deck screws are not suitable for redwood and cedar decking. This is due to the fact that the composite tannic acids used in treating them can corrode most corrosion-resistant screws. In cases like these, multicoated screws with proprietary anti-corrosion technologies are easily the best tools for the task.

With that said, it is important to know that irrespective of the coating applied, any screw can be corroded. The underlying difference is that while some might corrode quickly, others would take a very long time.

FAQs

What Screws are Best for Pressure Treated Wood?

The best screws for pressure treated wood are coated or multicoated screws with square-drive or Torx recesses, and the tips should either be serrated, fluted or auger tips. However, the design of the screw might be, it must be a corrosion-resistant screw; otherwise, the following results after decking might not be satisfactory.

ii. Do You Need Special Screws for Pressure Treated Wood?

Yes, you do. In the preservative-treated wood industry, stainless steel and hot-dip galvanized fasteners are the most recommended options for working on pressure treated lumber. It is important to ask for the composition of the chemicals used in treating the wood. This would help you determine the best screw to use on the lumber, with minimal risk of corrosion.

iii. Can I Use Galvanized Screws in Pressure Treated Wood?

Yes, you could. Hot-dip galvanized screws are generally recommended for woods treated with copper-based preservatives. Whether the wood is treated with traditional Chromated Copper Arsenate (CCA), Copper Azole (CAB), or Alkaline Copper Quat (ACQ), hot-dip galvanized screws are mostly preferred over stainless steel screws.

However, electroplated galvanized metal screws are not recommended for exterior applications.

iv. Is Pressure Treated Wood Safe for Decks?

Yes, they are. However, there are some Environmental Protection Agency (EPA) concerns over the safety of CCA-treated wood. Still, in the same line, EPA has also confirmed that by following simple maintenance and precautionary practices, CCA-treated wood can be regarded as safe for family use.

v. What Size of Deck Screw do I Need?

This is a bit dependent on the features of the wood you are working on regarding their width or thickness. However, the minimum length for deck screws is 2 ½ inches, though the commonly available screw size is 3 inches. The thickness of the surface should help you decide which screw to use.

Again, you need to check your screw gun. For more inspiration, you can read our best deck screw gun reviews.
