Where are clip on nut plates typically used in an assembly?

Clip on nut plates are primarily used near the edges of a part due to their design and functionality. Their placement in this area allows for effective fastening and load distribution when attaching components to the assembly. By situating nut plates near the edges, they can accommodate the natural stress and strain that occur at these points when the assembly is subjected to forces, such as vibration or tensile stress.

Furthermore, positioning them at the edges helps optimize the overall structural integrity of the assembly, ensuring that fasteners can be easily accessed for maintenance and that the attachment points are stable, reducing the likelihood of fatigue and failure over time. This strategic placement is essential in aerospace applications, where safety and reliability are paramount.

While the other options present various locations that could theoretically hold fasteners, none provide the collection of benefits associated with utilizing clip on nut plates at the edges of parts, such as improved load handling and ease of access.
