They're called both floorboard brads or brad nails (in most builder marchants in London) or cut nails, although the latter look a bit different when I search for them online. It maybe a regional variation, who knows. I can drive them in ok, but my partner said she prefers the pointy ones which i now realise are more likely to split the boards. Thanks for the learned advice I always learn something new when I post here.That is what we call a cut nail, so called because they are cut out of a flat ribbon of steel, hence the square ends (I realise that Amazon call them "brads", but I doubt many ironmongers or builders merchants on my neck of the woods would call them that) . If you are struggling to drive them I suggest you try a heavier hammer, or switch to oval nails which are less traditional, but which can be driven with a lighter hammer. Just blunt them first.
I went and had a look at what on-line retailers sell as "cut nails". More than half the examples I found were actually wrought nails. The difference is that wroughts were an earlier technology and were originally hand wrought by a local blacksmith. Later on nail making became a separate trade (especially around Cradley and Netherton in the Black Country) but the same process was used with manufacture if that type of nail dying out in the 1860s (at least based on listed buildings I've worked on) due to cut nails being cheaper to make. It seems to be another example of the people selling stuff not knowing how things are made or used...although the latter look a bit different when I search for them online. It maybe a regional variation, who knows
I'm starting to think that a lot of this knowledge, which was all part of the trades at one time, is being lost. The reason I need to know this stuff is that part of my work is on listed buildings these days (that, and being old enough to have been taught this stuff...)...my partner said she prefers the pointy ones which i now realise are more likely to split the boards.
Ooh, no, not American at all! Screw sizing in the UK was always based on Nettlefolds (later part of GKN) sizes from the Victorian period onwards. No. 8s are more like a 4.0 or 4.5mm metric screws (technically they have a 4.2mm shank and require a 3.5mm pilot hole). Pretty much all the screws we use these days are metric with the exception of brass and bronze screws, which tend to be old stock wherever possible...3.5 x 50 screws, 8 gauge by 2 inch in American lingo.
