8mm Timber Sleeper Screws

TIMCO IN-DEX 8mm Timber Sleeper Screws are heavy-duty fixings designed for exterior timber-to-timber applications, making them well suited to landscaping projects involving timber sleepers and other substantial outdoor timber structures. With an 8mm diameter and a range of lengths available, these screws provide a practical fixing solution where secure clamping of timber components is required.

Designed as an alternative to traditional coach screws, these timber sleeper screws are particularly suitable for fixing railway sleepers, landscaping sleepers, retaining walls, raised beds and other outdoor timber structures. The range provides several length options, allowing you to select a suitable screw for the timber thickness and requirements of your project.

The screws feature a 50° deep single thread designed to provide high pull-out resistance and a secure connection. A lubricated finish helps make insertion easier, while the helix shank is designed to remove timber debris during installation and improve clamping between the components being fixed.

A single slash point helps reduce driving torque and minimise timber splitting, making installation more efficient. The wafer head provides a secure fixing with a neat finish, while the TX30 recess is designed for installation using a TX30 driver bit.

The standard 8mm wafer head range is available in 200mm, 225mm, 250mm and 300mm lengths, with pack quantities varying by size. Stainless steel wafer head versions are also available in 125mm and 150mm lengths, providing an option where enhanced corrosion resistance is required.

The screws are tested to withstand 1,000 hours of salt spray, making them suitable for exterior landscaping and timber applications. Whether you're a professional landscaper, garden designer, contractor or DIY gardener, these 8mm timber sleeper screws provide a purpose-designed fixing option for a wide range of outdoor timber projects.
