Timber Sleeper Screws 6.7mm

Secure timber sleepers and other exterior timber-to-timber applications with TIMCO IN-DEX 6.7mm Timber Sleeper Screws. Specifically designed as a high-performance alternative to traditional coach screws, these corrosion-resistant exterior timber screws provide strong, reliable fixing for landscaping projects. With a 50° deep single thread, the screws offer high pull-out resistance, helping create a secure and durable connection when installing timber sleepers.

Designed with features that make installation quicker and easier, these sleeper screws are lubricated to reduce insertion effort and save installation time. The helix shank helps remove timber debris while improving clamping, while the single slash point is designed to reduce driving torque and minimise the risk of timber splitting. Hex head versions are available across a comprehensive range of lengths, alongside wafer head options with a TX30 recess, providing flexibility for different sleeper and timber applications.

Tested to withstand 1,000 hours of salt spray in accordance with BS EN 9227:2012, these screws provide corrosion resistance for demanding exterior environments. Available in a wide range of lengths from 75mm to 250mm in the 6.7mm diameter range, they are suitable for fixing timber sleepers and a variety of other outdoor timber-to-timber applications.
