What is the primary purpose of structural screws in aviation?

The primary purpose of structural screws in aviation is to assemble structural parts. These screws play a crucial role in ensuring that components of an aircraft’s structure are securely fastened together, providing the necessary strength and stability to withstand various stresses and loads during operation. Their design allows them to create tight connections, which is vital for maintaining the integrity of an aircraft's framework. Proper assembly using structural screws is essential for safety, as any failure in these connections could lead to catastrophic structural issues while in flight.

While aesthetic appeal, insulation, and supporting electrical components are important in other contexts, they are not the main functions associated with structural screws in aviation applications. Structural screws focus primarily on the integrity and assembly of the airframe and other key parts to ensure overall performance and safety.
