Metal hog rings are designed to ensure safety and a firm hold, while at the same time allowing a high application speed depending on the type of hog ring tool used. The absence of the exposed points typical of the handmade solutions often used in this field, such as fastening with twisted iron wire, makes them extremely safe. Their shape, and the range of internal diameters from 1 to 15 mm, make them, for example, the perfect tool for the stable fastening of wires. In terms of materials, there are hog rings in galvanised iron, aluminium, zinc-aluminium or stainless steel – a choice that ensures the long-lasting durability of the fastening in any kind of application.
