Reviews

Nicholas

Great Pack of Exterior Screws

Really impressed with these screws. We used them for a complete fascia and gutter replacement and they made fitting all the black rainwater components straightforward. They're sharp, drive in without needing excessive force and provide a strong fixing. The black heads are a small detail but make the finished installation look much better, particularly on the downpipe clips where the screws are clearly visible.

Michael

Ideal for Gutter Brackets and Downpipe Clips

These are now our go-to screws for black rainwater installations. They drive in cleanly, hold extremely well and the black finish makes the fixing almost disappear once fitted. We've used them for both gutter brackets and downpipe clips with excellent results.

John

Strong Fixing and a Much Neater Finish

Bought a pack of these when installing new black guttering on our garage. They went into the timber fascia easily and pulled the brackets up securely. I particularly like the low-profile head as it sits neatly against the fitting without looking bulky. Having 300 in the pack means there are plenty left for the downpipe clips and future jobs too.

MARK

Good Quality Fixings for Rainwater Jobs

We use these regularly for fitting PVCu gutter brackets and downpipe clips. They're a good solid screw with plenty of grip, and the 40mm length works well for most of our everyday rainwater installations. The black pan head gives a much better finished appearance on black guttering than a standard screw, especially where the fixings remain visible.

Lynne

Perfect Screws for Black Guttering

Used these screws while replacing the black guttering and downpipes around our house. The black low-profile heads blend in really well with the brackets and look much neater than using standard silver screws. They drive in easily and grip the timber securely without feeling like they're going to split it. The corrosion-resistant coating is also reassuring for something that's permanently exposed to the weather. Brissco were very helpful when ordering and made sure we had all the gutter fittings and fixings needed for the job. Everything arrived together and on time. Great service.
