Best Screws to Use for Pressure Treated Wood in Construction Projects

To build a pressure-treated wood deck or structure that’s both robust and enduring, it’s essential to employ superior screws that can form a resilient bond. Corrosion-resistant screws, such as stainless steel or hot-dipped galvanized options, boast the necessary resilience to counteract the treated wood’s inherent corrosive properties. When selecting screws for pressure-treated wood, consider the square drive, coarse thread, and wood point type.

For instance, specialized screws like Deckfast’s stainless steel offerings, designed for hardwoods like redwood and cedar, deliver exceptional hold. By selecting the optimal screws, you can construct a structure that defies the passage of time and stands the test of wear and tear.

What’s the Difference between Coated and Non-coated Screws for Pressure Treated Wood?

When working with pressure treated wood, it’s essential to use the right type of screws to ensure a strong and durable connection. Two popular options are coated and non-coated screws. But what’s the difference between them?

Coated Screws

Coated screws are designed with a special coating that helps protect the screw from corrosion and rust. This coating is typically applied to the screw’s threads and head. Coated screws are ideal for pressure treated wood because they reduce the risk of screw failure due to corrosion.

Non-Coated Screws

Non-coated screws, on the other hand, are not treated with a special coating. Instead, they are made from high-quality materials that resist corrosion. However, they may still be susceptible to corrosion, especially in harsh environments or when exposed to moisture.

Comparison

Here are some key differences between coated and non-coated screws for pressure treated wood:

  • Corrosion resistance : Coated screws offer better corrosion resistance than non-coated screws.
  • Durability : Coated screws tend to be more durable and longer-lasting than non-coated screws.
  • Cost : Non-coated screws are generally less expensive than coated screws.

Can I Use Regular Wood Screws for Treated Lumber?

When it comes to building or repairing things with treated lumber, one question that often arises is whether you can use regular wood screws. The short answer is: no, you shouldn’t.

  • Treated lumber is designed to withstand harsh conditions and resist rot, decay, and insect damage. Regular wood screws are designed for use with untreated wood and may not be able to penetrate the treated lumber effectively.
  • Treated lumber has a protective coating that can interfere with the screw’s ability to hold properly. This can lead to the screw head stripping or the screw coming loose over time.
  • Using regular wood screws with treated lumber can put unnecessary tension on the screw, which can cause it to break or split the wood.
  • Galvanized or stainless steel screws are good options for use with treated lumber.
  • Look for screws specifically labeled as “treated lumber screws” or “pressure-treated screws” for the best results.

How Do I Choose the Right Screw Length for Pressure Treated Decking?

Choosing the right screw length for pressure treated decking can seem daunting, but with a few simple steps, you’ll be on your way to a sturdy and long-lasting deck.

Measure the Decking Boards

Measure the thickness of the decking boards you’ll be using. Typically, pressure treated decking boards range from 1″ to 2″ thick.

Check the Screw Type

Check the type of screw you’ll be using. Most deck screws are either galvanized or stainless steel. Galvanized screws are sufficient for most home projects, but if you’re building a deck for commercial use or in an area with high salt or moisture exposure, stainless steel screws may be a better option.

Determine the Screw Length

Using your measurements, determine the screw length needed to secure the decking boards. A general rule of thumb is to choose a screw that’s 1-2 threads longer than the thickness of the decking board. So, if your board is 1 1/2″ thick, choose a screw that’s 1 3/4″ to 2 1/4″ long.

Additional Considerations

  • Check the manufacturer’s recommendations for screw length and type.
  • Consider using screws with a corrosive-resistant coating for added protection.
  • Always check the screw head is countersunk to avoid protrusions and ensure a flush surface.

Can I Use Pressure Treated Wood for Fencing and Which Screws Should I Use?

Pressure treated wood is a common choice for fencing due to its durability and resistance to rot and insects. However, it’s essential to consider the type of fencing you’re building and the environmental factors it will face.
