How many should I order?

Count fastening points along the full gutter run and add a few spares.

#12 x 4″ Tek Screw with Sealing Washer for Pergola Gutter

This #12 x 4″ hex washer head Tek screw is stainless steel and comes with a sealer washer. The Aluglobus Aluminum Systems price list names it as the fastener for the pergola gutter.

Where It Fits

Our pergola parts range includes aluminum gutter profiles, beams, posts, LED channels and U-channels. This screw is the one listed for the gutter connection. The price list does not tie it to a specific gutter profile, so confirm your gutter with our team if you are unsure.

Ordering Tips

Count fastening points along the full gutter run and add a few spares.
Order replacements whenever you replace a sealer washer or a damaged screw.
Follow the included instructions and local code for your structure.

A sealer washer is the usual choice wherever a fastener passes through a surface that carries water, such as a gutter. Because the screw is 4″ long, check that it suits the gutter and beam connection you are making, and ask our team to confirm if your layout differs from the standard system. Keep a few spare screws and washers with your pergola hardware.

"I couldn't be happier with the fence. From the moment it went up, it completely transformed my backyard. The sleek design without visible posts gives it such a modern, high-end look. It's like having a piece of art around my home. I also love that it's fire-resistant, which gives me peace of mind living in this area. Definitely worth every penny!"
