Understanding Deck Screws: Everything You Need to Know

Deck screws are a crucial component in outdoor construction, providing the strength and durability needed to secure decking materials. Whether you're building a new deck or maintaining an existing one, understanding the specific properties and uses of deck screws is essential. In this article, we'll cover the most frequently asked questions about deck screws to help you make informed decisions for your project.

General Overview of Deck Screws

Deck screws are specifically designed for outdoor use, offering several advantages over traditional nails and other fasteners. Made from corrosion-resistant materials such as stainless steel or coated steel, deck screws are built to withstand the elements and ensure the longevity of your deck. Their design includes features such as sharp points and deep threads, which provide strong holding power and ease of installation.

Frequently Asked Questions About Deck Screws

  • Are deck screws structural?

    • Deck screws are not typically considered structural fasteners. They are designed to hold decking materials in place but are not meant to bear heavy loads like structural screws or bolts. Standard deck screws are not and should not be confused with dedicated structural screws. 
  • Can deck screws be used with pressure-treated wood?

    • Yes, deck screws can be used with pressure-treated wood. It’s important to choose screws that are specifically designed for use with pressure-treated lumber to prevent corrosion like our Max Drive products.
  • How do I prevent deck screws from stripping?

    • To prevent deck screws from stripping, use a high-quality screwdriver or drill bit that matches the screw head. Applying consistent pressure and driving the screws slowly can also help avoid stripping.
  • Should I pre-drill holes for deck screws?

    • While many deck screws are self-tapping and do not require pre-drilling, pre-drilling can help prevent the wood from splitting, especially near the ends of boards or in hardwoods.
  • What type of coating should deck screws have?

    • Deck screws should have a corrosion-resistant coating, such as stainless steel or a weather-resistant coating, to withstand outdoor conditions and prevent rusting.
  • How do I choose between stainless steel and coated deck screws?

    • Stainless steel screws offer superior corrosion resistance and are ideal for coastal or high-moisture environments. Coated screws are generally more economical and still provide good resistance to corrosion for most outdoor applications.
  • Can I use deck screws for other outdoor projects?

    • Yes, deck screws can be used for various outdoor projects such as fencing, pergolas, and outdoor furniture, as long as the screws are appropriate for the materials and loads involved.
  • What is the best way to remove old deck screws?

    • To remove old deck screws, use a screwdriver or drill with a matching bit. If the screw is stripped, you may need to use a screw extractor or a pair of pliers.
  • Are deck screws strong?

    • Yes, deck screws are strong and designed to resist the forces they encounter in deck construction, including lateral and withdrawal forces. Their corrosion-resistant coatings also enhance their durability.
  • Are deck screws the same as wood screws?

    • While both are used in woodworking, deck screws are specifically designed for outdoor use with enhanced corrosion resistance and additional features like sharp points and deep threads to handle the stresses of outdoor environments.
  • Are deck screws self-tapping?

    • Many deck screws are self-tapping, meaning they can create their own pilot hole as they are driven into the material. This feature simplifies installation and reduces the risk of splitting the wood.
  • Can deck screws be used for framing?

    • Deck screws are not recommended for framing, as they are not designed to handle the heavy loads and stresses involved in structural framing. Use appropriate structural screws or nails for framing purposes.
  • How many deck screws do I need?

    • The number of deck screws you need depends on the size of your deck and the spacing of your deck boards. As a general rule, plan for two screws per joist per deck board. As a general guideline, 350 deck screws for every 100 square feet of decking installed. For this estimate, we are assuming a standard 5-1/2" to 6" boards with a standard 16" joist spacing.
  • How many deck screws per board?

    • Typically, you will need two screws per joist per deck board. For example, if your deck boards span three joists, you will need six screws per board.
  • Why use deck screws?

    • Deck screws offer superior holding power, are resistant to corrosion, and reduce the risk of splitting the wood. They also provide a cleaner and more secure connection compared to nails.
  • Where to place screws on deck boards?

    • Place deck screws about 1 inch from the edges of the deck board and 1 inch from the ends. This helps prevent splitting and ensures a secure attachment.
  • What length deck screws?

    • The length of deck screws depends on the thickness of your deck boards. For standard 5/4 inch decking, 2.5-inch screws are commonly used. For thicker decking, such as 2-inch boards, use 3-inch screws.
  • What size deck screws for 2x6?

    • For 2x6 deck boards, use 3-inch deck screws. This length ensures the screw penetrates deep enough into the joist to provide a strong and secure hold.


Deck screws are an essential component for any deck building project, providing the strength, durability, and ease of installation needed for long-lasting outdoor structures. Understanding the differences between deck screws and other types of screws, their specific uses, and proper installation techniques will ensure your deck remains secure and beautiful for years to come.
