Timber Sleeper Screws 8mm

Secure heavy-duty timber landscaping projects with TIMCO IN-DEX 8mm Timber Sleeper Screws, specifically designed for exterior timber-to-timber applications. These robust screws provide a strong and reliable alternative to traditional coach screws, making them ideal for fixing timber sleepers, retaining walls, raised beds and other outdoor timber structures. The 8mm diameter provides a substantial fixing for demanding landscaping applications where strength and secure clamping are essential.

Featuring a 50° deep single thread, these sleeper screws are engineered to provide high pull-out resistance and a secure connection. The screws are lubricated to make insertion easier and faster, while the helix shank helps remove timber debris and improve clamping. A single slash point reduces driving torque and helps minimise timber splitting, making installation more efficient and helping protect the timber during fixing.

The 8mm range is available in 200mm, 225mm, 250mm and 300mm lengths, with wafer head options supplied in convenient packs. Stainless steel versions are also available in 125mm and 150mm lengths, providing an excellent option where enhanced corrosion resistance is required. The screws are tested to withstand 1,000 hours of salt spray, making them well suited to exterior landscaping applications and use with timber sleepers.
