For which purpose would you use barrel nuts?

Barrel nuts are specifically designed for use in applications where high tensile strength is required. These fasteners are typically used in situations that require a secure and strong connection between two components, such as in furniture assembly, structural applications, or when fastening parts that may experience significant stress. The unique design of barrel nuts allows them to provide a strong grip and resistance against pull-out forces, making them ideal for applications that must endure high loads.

Using barrel nuts not only maximizes the strength of the connection but also allows for a cleaner appearance since the fastener can be concealed within the material. This is essential in both structural engineering and aesthetic design, where both strength and visual appeal are significant considerations.

While barrel nuts may sometimes provide advantages in maintenance or specific applications like securing threaded rods or clevis bolts, their primary function is rooted in delivering the high tensile strength needed in robust mechanical assemblies.
