What are structural screws primarily used for?

Structural screws are primarily used for assembling structural parts because they provide the necessary strength and stability to hold the components of a structure together. In aviation and other engineering fields, the integrity of the assembly is crucial as it must withstand various loads and stresses encountered during operation. Structural screws are specifically designed to bear these loads and also facilitate ease of assembly and disassembly when required.

They are typically made from high-strength materials that ensure a robust connection and are often used in applications that may involve high levels of vibration or movement, which is common in aviation. Utilizing structural screws enhances the overall reliability and safety of the aircraft's structural integrity. This application distinguishes them from other fasteners that may serve different purposes, such as decorative elements or insulation, which do not serve the same critical function in maintaining structural integrity.
