Carpet pins, made of hardened steel, are preferably used in industry and in handicraft work. The stable pins with the ring-shaped, curved eye are ideal for affixing carpet rolls, for instance. Their conically-shaped stem has a length of 67 mm and is 1.6 mm thick. The eyelet not only allows for the carpet pins to be easily removed, but they are also great for fastening. Prym offers these strong pins in cardboard boxes with 100 units each.
