Timco Rainwater Screw - Exterior (Black Organic) 4.0 x 40

The Timco Rainwater Screw is the specialist fastener designed for the secure and durable installation of PVCu rainwater systems, including guttering, downpipes, brackets, and support clips. Its innovative engineering combines functionality with robust protection against the elements, making it an essential component for roofing contractors, builders, and skilled DIY enthusiasts undertaking rainwater installation projects.

Engineered for performance, each screw features a 25° sharp point with a single slash on the first 25mm of the shank. This design significantly reduces torque during insertion and minimises the risk of timber splitting, which is particularly beneficial when fixing close to the edge of a fascia board. The screw utilises a 40° deep single thread along 35mm of its length, providing exceptional grip and high pull-out resistance to ensure fittings remain secure in all weather conditions.

Durability is paramount for external fixings. These screws are treated with a high-quality corrosion-resistant exterior coating (Black Organic finish) that has been tested to withstand over 1,000 hours of salt spray testing, offering long-term protection against rust and degradation. This makes them perfectly suited for the harsh UK climate. The low-profile pan head sits flush against the fitting, and the PZ2 Pozi drive recess ensures a secure, cam-out resistant connection with your power driver for fast and efficient installation.

Supplied in a convenient and practical pack containing 300 pieces, this box offers excellent value for professional jobs or larger domestic projects. The compact box dimensions facilitate easy storage and transportation. By choosing Timco Rainwater Screws, you are selecting a purpose-built fastener that delivers reliable, long-lasting performance for any rainwater system installation.
