If you're a joiner, DIYer, landscape gardener, or someone working on outdoor projects, using the correct fixings is essential for ensuring durability and strength. At Next Day Fixings, we supply a complete range of timber and landscape screws, specifically designed for decking, fencing, wooden sleepers, sheds, pergolas, and other outdoor constructions.

Unlike traditional screws or nails, timber and landscape screws offer superior holding power, faster installation, and more excellent resistance to weather conditions. Whether you're working on hardwood or softwood, the right screw ensures a strong and lasting build.

This guide explores the different types of timber and landscape screws, explaining their benefits, materials, coatings, and applications.

Timber and landscape screws are specialized fixings designed for securing wood in outdoor environments. They are stronger than regular wood screws and come with deep threading, self-drilling tips, and weather-resistant coatings. These screws are essential for fencing, decking, raised garden beds, sleepers, and large wooden structures.

• Firmer grip: Deep threading provides excellent holding power.
• Corrosion-resistant: Protective coatings prevent rust and decay.
• Easy installation: Many designs don’t require pilot holes.
• Prevents splitting: Slash points reduce the risk of wood splitting.

• Hex Head Screws: Designed for high-torque applications, perfect for heavy-duty timber structures. Works best with impact drivers and power tools.
• Wafer Head Screws: Provides strong clamping force while maintaining a low-profile finish. Best for cladding, sleepers, and fencing.

• Exterior Green Coating: Ideal for general outdoor use, offering 1,000-hour salt spray resistance.
• Exterior Silver Coating: A more substantial, heavy-duty option without pilot holes.
• A2 Stainless Steel: Corrosion-resistant, excellent for moderate weather conditions.
• A4 Stainless Steel: The best choice for coastal and marine areas, offering extreme corrosion resistance.

The Hex Head Exterior Green Timber Screw is an upgraded alternative to traditional coach screws, offering faster installation, better grip, and superior weather resistance.

Selecting the correct timber screw for your project is crucial for ensuring a strong, long-lasting structure. Different outdoor projects require different screw types based on wood type, exposure to weather, and load-bearing needs. Below, we break down the best screws for decking, fencing, sleepers, raised beds, pergolas, and summer houses.

Decking and fencing are constantly exposed to outdoor elements such as rain, humidity, and temperature fluctuations. This means the screws used need high corrosion resistance, strong holding power, and the ability to securely fix timber without causing splitting.

Why Use Exterior Green Hex Screws?

• A corrosion-resistant green coating prevents rust and degradation.
• The hex head design allows for higher torque application, making installation easy with an impact driver.
• The self-drilling tip eliminates the need for a pilot hole in most softwoods.
• Deep-threaded design provides superior grip in decking boards and fence posts.

Best Uses:

• Installing timber decking securely to joists.
• Fixing fence panels and fence posts into place.
• Building wooden garden dividers or trellis systems.

Garden sleepers and raised beds require fixings that can handle weight, soil moisture, and long-term exposure to outdoor elements. Since wooden sleepers are often used for retaining walls, edging, and garden structures, they need screws that can resist corrosion, avoid splitting, and maintain a strong hold over time.

Why Use Hex Head Stainless Steel Screws?

• A2 or A4 stainless steel prevents rust, making them perfect for damp environments.
• The hex head with a built-in washer increases clamping force, preventing movement over time.
• The self-drilling point reduces timber splitting, even in dense woods like oak.
• Deep single thread ensures maximum grip in heavy timbers.

Best Uses:

• Building raised garden beds that are exposed to water and soil.
• Securing large timber sleepers in landscaping projects.
• Constructing wooden retaining walls for garden tiers.

Pergolas and summer houses are decorative and structural elements that need to be securely fixed while maintaining a clean, aesthetically pleasing appearance. Wafer head screws are perfect for cladding, timber framing, and securing beams without creating a bulky or noticeable fixing point.

Why Use Wafer Head Exterior Green Screws?

• Wafer head provides a low-profile finish, making them ideal for decorative structures.
• Green corrosion-resistant coating protects against the elements.
• The self-drilling tip allows for fast installation in softwoods and treated timbers.
• Even pressure distribution prevents timber from cracking under strain.

Best Uses:

• Assembling wooden pergolas in gardens or patios.
• Building summer houses or wooden sheds.
• Attaching cladding or decorative wooden panels.
