Wanted PIR roof screws to timber 150mm

[JonCamo]

Dear all

I am fixing a PIR roof for my lean to shed. I need some 150mm screws to fix to timber, the ones with a 16mm or 19mm bonded washer. I only need a few so don't want to buy a whole pack and have loads left over that I will never use.
Happy to pay a few quid, only need 5 to 10 if anyone can help

Regards

Jon

Personally I wouldn’t use those, in your situation I’d cut some big plastic washers with a holesaw from a bucket lid etc & fix them with ordinary long screws.

Nice idea. Cheers

Maybe add a rubber (plumbing type) washer under the plastic

I used long screws and squares of plywood as washers. I f gd ave them a coat of white primer paint and they are hardly noticeable!

Old fashioned rubber tap washers work.
