I was under the impression hot dipped galvanised is far superior, and best for any outdoor use...

I need to do some roof repairs and bought a pack of round wire nails made by Samac, for fixing sarking boards and battens to rafters. The Samac nails are sold in several roofing stores so I presumed they were exactly what I need. But it turns out they are zinc coated. And one reviewer on Amazon says he used them outdoors and they rusted quickly.

Hoping to get started on that part of the roof tomorrow. Do I need to go and buy some different nails (if I can find some locally)? Or go ahead with what I've got?

There doesn't seem to be a price difference between the two, so if hot dipped are better, I'm confused as to why so many roofing stores only sell zinc coated round wire nails? Is there a downside to hot dipped?

Many thanks]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303775#Comment_303775 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303775#Comment_303775 Fri, 06 Oct 2023 18:14:21 +0100 revor These were used for battens, for the slates we used copper. Not having a zinc nail in front of me I would guess they are smoother than a galvanised nail. I think the hot dipped will grip better in the timber.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303777#Comment_303777 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303777#Comment_303777 Fri, 06 Oct 2023 19:06:38 +0100 owlman http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303778#Comment_303778 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303778#Comment_303778 Fri, 06 Oct 2023 19:20:41 +0100 Artiglio http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303780#Comment_303780 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303780#Comment_303780 Fri, 06 Oct 2023 22:36:47 +0100 chrisinbrighton Hot dipped galvanised is the only way..or stainless ?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303781#Comment_303781 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303781#Comment_303781 Sat, 07 Oct 2023 09:39:44 +0100 greenfinger
It does leave me wondering though... If hot dipped are so much better, why do people choose to use (and roofing stores choose to sell) the far inferior electro zinc coated? Samac were very quick to assure that they were perfectly fine for fixing battens. They don't even make hot dipped nails...

I canly find nuts/ bolts or nails that are hot dipped

I have looked in the past and failed, nearest can get to screws is coach bolts with square or hex heads. Suspect if you hot dipped the screw the slots/drive heads would get filled but don't know if that is the reason. I would normally got to stainless and cut the thread with a conventional screw of similar size first.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303793#Comment_303793 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303793#Comment_303793 Sat, 07 Oct 2023 19:23:18 +0100 owlman Posted By: chrisinbrightonOn a similar subject,has anyone found a supplier of hot dipped galv countersunk woodscrews?

You can get them Chris, but limited choice, imperial sizes, often old stock, and expensive.

I guess stainless is an option but they are very soft

I have only stainless screws exposed on our build. Gutters and downpipes are fixed with stainless round headed self tappers and fascia and soffit boards with countersunk even if they are covered with trims. Whilst they can be soft pilot holes and tapping with conventional screw first, avoids shearing. Our satellite dish is on an outbuilding so to avoid that rusting and staining our render on the house. Ducting underground brings the cable into the house. All soil pipes underground as well as all other services. Earlier this week watched a Grand Designs (repeat) programme of a very expensive build close to the sea shore on the Isles of Wight. They had some expensive timber cladding but within months the staining around the nail fixings was really bad particularly around the bottom where the rain and salt ends up. It really spoilt the look. some say it added character but for how long until the nail has rusted so much that boards come loose?. Bad attention to detail on I think was a £3 mio build. We are close to the sea and examples all around me of bad staining on new builds within months from rusting fixings.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303806#Comment_303806 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17987&Focus=303806#Comment_303806 Sun, 08 Oct 2023 09:43:55 +0100 greenfinger
With regards SS screws, I don't want to complicate things but are there different grades? Or are all SS screws made equal?
