Dome Wire Coil Nails
When looking at the coil of nails, conical nails will be layered from the outside of the coil towards the center, creating a 'Cone', or domed shape. In such a coil the nails are layered from the outside of the coil to its center to form a cone. These coils are used in specially adapted cone coil nail guns. Using the wrong kind of coil in such a nail gun might lead to jamming, misfire, or even an injury. Conical coil nails are welded together by two thin wire strips at a slanted 15-degree angle.
