In-Dex Timber Screw

Strong Screws for Heavy Timber Work

In-Dex Timber Screw provides a powerful and secure fixing option for heavy-duty timber projects. The screw features a 6.7 x 175mm design, which offers excellent grip and deep penetration into structural timber. The green organic finish improves corrosion resistance, and the TX30 head provides strong engagement with the included driver bit. As a result, the screw delivers consistent and reliable performance on site.

Designed for Structural Timber Fixing

The long length makes the screw suitable for landscaping timber, sleepers, posts, framing and heavy exterior construction. The sharp point starts quickly and helps reduce splitting, even in dense timber. In-Dex Timber Screw works well in softwood and pressure-treated timber, and it supports long-lasting structural strength. The screw is ideal for both professional contractors and DIY users handling outdoor installations.

Easy and Controlled Installation

The TX30 head provides excellent torque transfer, and this helps prevent cam-out during driving. The included driver bit adds convenience and supports consistent engagement. The screw cuts cleanly into timber, which improves stability and reduces the need for pre-drilling in most applications. Moreover, the coarse thread increases holding power and helps secure large timbers tightly.

Durable for Exterior Conditions

The green organic coating offers strong protection against rust and weather exposure. This makes the screw suitable for garden structures, fencing, retaining walls and general exterior timber work. The box of 50 provides good value for larger jobs that require repeated heavy fixings. The design ensures long-term reliability in demanding environments.
