Barrel Nut

The barrel nut, also referred to as a steel cross dowel or dowel nut, is a specialized type of nut that finds widespread use in the aerospace industry as well as in ready-to-assemble furniture applications. This unique nut design serves crucial purposes in holding together various components in these industries, making it an indispensable fastener for many operations. Its popularity can be attributed to the ease of installation and formidable strength, which makes it a go-to option for applications where reliability and durability are a must.

A barrel nut is commonly used to secure delicate sheet metal parts onto larger billet or forged components. This unique nut is typically a round slug or a shaped sheet metal piece with threads running perpendicular to its length. When employed, the barrel nut is positioned within a hole in the forging, and a regular bolt is then threaded into it from the outside of the sheet metal. The advantages of using barrel nuts over traditional nuts and bolts are manifold. Firstly, they eliminate the need to machine or forge a flange onto the receiving part, which effectively reduces the overall weight of the assembly.
