6.7mm Timber Sleeper Screws

TIMCO IN-DEX 6.7mm Timber Sleeper Screws are designed for securing timber sleepers and other exterior timber-to-timber applications. Developed as a high-performance alternative to traditional coach screws, these exterior timber screws provide a practical fixing solution for landscaping, garden construction and outdoor timber projects.

With a 6.7mm diameter and a 50° deep single thread, these timber sleeper screws are designed to provide high pull-out resistance and a secure connection between timber components. They are particularly suitable for fixing railway sleepers, oak sleepers, raised beds, sleeper retaining walls and other outdoor timber structures.

The screws feature a lubricated design to help reduce insertion effort and make installation quicker and easier. The helix shank helps remove timber debris from the hole while improving clamping, while the single slash point is designed to reduce driving torque and help minimise timber splitting during installation.

A comprehensive range of lengths is available, from 75mm through to 250mm in the hex head range. Wafer head versions are also available in 95mm and 150mm lengths, featuring a TX30 recess for applications where a wafer head fixing is preferred.

The screws have been tested to withstand 1,000 hours of salt spray in accordance with BS EN 9227:2012, providing corrosion resistance for exterior applications. Supplied in packs of 50, they are a convenient choice for both professional landscaping projects and DIY garden construction.

Whether you're securing railway sleepers, building a sleeper retaining wall, creating raised garden beds or working on another exterior timber project, these 6.7mm timber sleeper screws offer a purpose-designed fixing solution for suitable timber-to-timber applications.
