When the UK made a wide range of high quality screws etc. NB Pre-GKN.
I bought these from a local builders merchant in about 1980: boxes of old stock on the counter sold at knock-down prices. Really well-made screws, and what amuses me is the description Dark Florentine bronzed; at least implying that you could buy a lighter shade!

I have just notice this thread today, Sunday. I believe GKN started making screw circa 1902- 1905, using the brand name Nettlefolds, later changed to GKN. I have a copy of their screw department catalogue dated 1927 and they were still making screws up to 40G (yes, forty gauge) when I started my apprenticeship in 1956. I was instructed thus about screws: - To find the gauge measure across the head in 1/16”s, then multiply by 2 and, finally, deduct 2. For example, 6/16” x 2 = 12, deduct 2 = 10 gauge.
As screws are parallel lengthways, I was only allowed to hammer a screw in the length of the plain bit of the shank as this punched a hole into the timber to fit the plain bit of the shank. This doesn’t work with modern screws. If we were using brass screws on brass fittings, we always used steel ones first and then changed them to brass as it prevented snapping any off. Depending on size, they were boxers in grosses; ½ and ¼ grosses. For younger readers, 1 gross = 144.
Nettlefolds made an amazing range of screws whereas, nowadays, it is hard to get some sizes. Currently, I believe that most screws are made in Vietnam, apart from Reisser and Spax, which are made in Germany and are very good quality.
