6.3 x 45mm Metal-to-Timber Roof Screws

Reliable Roofing and Cladding Fixings

6.3 x 45mm Metal-to-Timber Roof Screws provide a strong and dependable fixing option for thin sheet metal to timber. Each screw includes a hex head, an EPDM washer and a sharp slash point designed for quick installation. The silver organic coating gives excellent corrosion resistance, which supports long-term outdoor performance. The box of 100 offers great value for trade and DIY roofing projects.

Designed for Metal-to-Timber Use

The screws are ideal for fixing metal sheets, flashings and cladding panels to timber structures. The 45mm length is suitable for thinner timber frames or areas where a shorter fixing is needed. The slash point helps start the screw quickly and reduces the risk of timber splitting. 6.3 x 45mm Metal-to-Timber Roof Screws work well in agricultural buildings, sheds, workshops and stable roofs that require secure sheet fixing.

Fast and Efficient Installation

The hex head allows high torque control and supports a stable drive with standard tools. In many cases, the screw can be driven without pre-drilling, which saves time on site. The EPDM washer forms a tight seal against weather and moisture. This helps protect both the timber frame and internal structure from water ingress.

Built for Exterior Conditions

The silver organic coating gives durable protection against rust, making these screws suitable for exposed and high-moisture environments. The washer maintains a weatherproof seal over time, even with repeated expansion and contraction of roofing sheets. The box of 100 ensures you have enough fixings for small and medium-sized roofing or cladding tasks.
