Rainwater Screws – PZ – Low Profile Pan – Exterior – Black

These black rainwater system screws are made specifically for fixing brackets and clips during PVCu gutter and downpipe installation. Where a lot of screws get pressed into service across different jobs, these are purpose-built for one thing and do it well. The low profile pan head sits flush against the bracket face without fouling the system, and the black finish keeps things looking tidy once the job is done.

The 40-degree deep single thread gives a solid fixing with high pull-out resistance, which matters when guttering takes the full weight of water and debris over winter. The corrosion resistant coating is rated to 1,000 hours salt spray, so these will hold up on exposed elevations and coastal sites without corroding through the bracket over time.

Why the Thread Design Matters on Black Rainwater System Screws

Fixing brackets close to the edge of a fascia board is where cheaper screws cause problems. These screws include a single slash on lengths of 25mm and above, which reduces torque during driving and significantly lowers the risk of splitting the timber. On older fascia boards or hardwood, that small detail saves a lot of aggravation.

Fixing Into Masonry

When fixing directly into brick or blockwork rather than timber, use a 7mm brown wall plug. The screws are not self-tapping into masonry, so the plug is essential for a secure fix. Pre-drill to the correct depth, fit the plug flush, and drive the screw home.

Available in multiple sizes and pack quantities, including a 300-piece tub option for those fitting an entire system in one go. These are a staple trade fixing for roofers, builders and general maintenance contractors who install rainwater systems regularly.
