What type of fasteners should be used to prevent cap strip separation?

Using screws as fasteners to prevent cap strip separation is effective because screws provide a strong mechanical connection between the cap strips and the underlying structure. This mechanical connection helps resist shear and tensile forces that could otherwise cause the cap strips to separate over time.

Screws have a threaded design that allows them to grip the materials more securely compared to other fasteners. This gripping action creates a tight bond that enhances the overall stability of the assembly, making it less prone to separation due to vibration or loading conditions often encountered in aviation operations.

Other fasteners like wooden dowels and nails might not provide the same level of strength and retention, as dowels rely on glue for adhesion and can become loose over time, while nails typically do not offer the same holding power as screws. Epoxy bonds are strong but may not allow for easy disassembly or adjustments in the future. Therefore, screws are the preferred choice for ensuring a reliable and strong bond that can stand up well to the demands of aviation environments.
