Why are nut plates used in areas lacking accessibility for traditional nuts?

Nut plates are specifically designed to provide a secure fastening option in situations where traditional nuts cannot be easily accessed. In aerospace applications, where reliability and safety are paramount, having a robust connection is essential. Nut plates are typically installed in pre-drilled holes and can be attached to a structure, creating a reliable anchor point for bolts or screws. This is particularly useful in tight spaces or areas that are difficult to reach, where conventional nuts would be hard to handle and torque properly.

The advantage of nut plates in these inaccessible areas is that they allow for a secure and long-lasting connection without requiring extensive access for fastening tools, which is vital in ensuring the integrity of the assembly. By facilitating a secure fastening method while overcoming the challenges of limited accessibility, nut plates play a crucial role in maintaining the structural integrity of aerospace components.
