What is the primary purpose of structural screws?

The primary purpose of structural screws is to assemble and secure structural components within an aircraft. These screws are critical in ensuring the integrity and stability of various structural elements, such as fuselage frames, wing attachments, and tail sections. By fastening components together, structural screws help distribute loads and stresses evenly across the aircraft structure, which is essential for maintaining the safety and performance of the aircraft during flight.

In the context of aviation, the use of proper screws is governed by strict specifications and standards to ensure that they can withstand the significant forces experienced in flight, as well as environmental factors such as temperature changes and corrosion. The correct selection and installation of structural screws contribute significantly to the overall durability and reliability of the aircraft's design.
