Slot-headed and self-coloured, made possible by Victorian engineering and the invention of the screwdriver but now hard to find. Look good where cross-headed, plated screws don’t do justice to the the efforts to get everything else looking right. The stock we keep are 10gauge (3.5mm), from half an inch to one-and-half (20mm, 25mm, 30mm and 35mm). We’ll send 30mm unless you e-mail us requesting something else. They come in boxes of 100 but if you don’t need that many, drop us an e-mail. (and they’re NOT original Nettlefolds, sadly)
