Barrel Nuts sometimes called Dowel Nuts, are specialized nuts commonly used in aerospace and ready-to-assemble furniture applications. A barrel nut is a round slug, or formed sheet metal part with threads perpendicular to the length of the nut and are used to bolt thin sheet metal parts to larger, often billet or forged, parts.
