What is a major advantage of using one-legged nut plates?

One-legged nut plates are specifically designed to minimize protrusion, which is a significant advantage in aerospace applications where space is often at a premium. By utilizing a configuration that allows one leg to fit into a panel or structure, these nut plates can effectively secure components while keeping the overall profile compact and streamlined.

This minimal protrusion is essential in preventing interference with adjacent parts, reducing drag, and improving the aerodynamic efficiency of the assembly. Additionally, the reduced footprint helps in maintaining the structural integrity and design aesthetics of the aerospace application by allowing for greater flexibility in the arrangement of components.

In other contexts, the other choices could pertain to different considerations in component design, but they do not directly relate to the functional benefits realized from the unique configuration of one-legged nut plates.
