Decking Screws.

What are Decking Screws?

Decking screws are specialised self-tapping fasteners designed to secure decking boards to timber framework, ensuring a sturdy and long-lasting outdoor structure.

These specific wood screws are engineered with a sharp point and deep, aggressive threads that provide maximum holding power. Their threads are designed to bite into the wood or composite material, preventing the boards from lifting or warping over time. They often feature a countersunk head, allowing them to sit flush with or below the surface of the deck, creating a smooth and aesthetically pleasing finish.

How Decking Screws Work.

Decking screws are essential for both wood and composite decking installations. When installing a deck, these screws are driven through the decking boards and into the underlying joists. This not only holds the boards in place but also helps distribute the load across the structure, enhancing stability.

For composite decking, composite deck screws are specifically designed to work with the composite materials, reducing the risk of splitting, removing any material build-up under the head and ensuring a secure fit.

Real-life applications include securing outdoor decks, patios and even dock constructions. The correct installation of these screws ensures a neat, professional finish and contributes to the overall safety and durability of the deck.

Materials Decking Screws Are Made From.

Accu's range of decking screws is available in various materials, each suited for specific environments and applications.

Stainless steel deck screws, including A2 and A4 stainless steel options, are highly resistant to corrosion, making them ideal for outdoor use in harsh weather conditions. 305 stainless deck screws are another excellent option, offering a balance between strength and corrosion resistance.

For those seeking a specific aesthetic or additional corrosion resistance, our range has options for black decking screws or green anti-corrosion finishes. These finishes not only enhance the appearance when using darker stained wood but the green decking screws also provide extra protection against rust and corrosion.

What Size and Type Decking Screws Are Available.

At Accu, decking screws come in a wide range of sizes to accommodate various decking needs. The smallest thread size available is 3.8mm, perfect for more delicate applications, while our deck screws for composite decking offer the largest at 4.8mm, providing extra strength for heavy-duty installations.

The range varies in length from 25mm to 90mm, ensuring you have the right length for securing different thicknesses of decking boards.

We offer several drive types, including Torx, Pozi and Square (Robertson), which provide better torque and reduce the risk of cam-out. Head types include the commonly used countersunk head for a flush finish and the button pan head for a decorative look.

For those working with composite decking, our range of composite deck board screws is specifically designed to prevent mushrooming and provide a clean, professional finish. Additionally, our selection includes different enamel-coated heads in grey, black and brown for a sleek, modern aesthetic.

FAQs.

Q: What screws should you use for decking?.

A: For decking, it is best to use screws specifically designed for this purpose. They offer better-holding power and are usually made from corrosion-resistant materials like stainless steel with additional green anti-corrosion coatings. Depending on the decking material, you can choose from wood/timber decking screws or composite decking screws.

Q: Is it better to nail or screw decking?.

A: Screwing decking boards is generally preferred over nailing. Screws provide a stronger, more secure hold and are less likely to loosen over time. They also prevent boards from lifting or warping, ensuring a longer-lasting and safer deck structure.

Q: What is the difference between decking screws and normal screws?.

A: Decking screws are specifically designed with features such as sharp points, deeper threads and corrosion-resistant materials, making them suitable for outdoor environments. Normal screws may lack these specialised attributes, which can lead to reduced performance and durability when used in decking applications.

Q: Do you pre-drill deck screws?.

A: Pre-drilling is recommended, especially for hardwood or composite decking, to prevent splitting and ensure a clean, accurate installation. Some decking screws are self-drilling, but pre-drilling can still be beneficial in providing a better finish and easier installation.

Q: Should you countersink deck screws?.

A: Yes, countersinking deck screws is advisable, especially when installing composite decking. This technique allows the screw head to sit flush with or below the surface of the decking board, providing a smooth finish and reducing the risk of damaging the boards. It also enhances the overall aesthetic of outdoor spaces.
