Barrel nuts are a type of fastener that are commonly used in construction and woodworking projects. They are designed to be used with a bolt or screw and provide a secure and stable connection between two pieces of material. Barrel nuts are often used in situations where access to one side of the connection is limited, as they can be installed from only one side. They come in a variety of sizes and materials, including stainless steel, brass, and zinc-plated steel. Barrel nuts are an essential component for any DIY enthusiast or professional builder looking to create a strong and reliable connection.
