Which tool is used to clamp the stringers into place on the assembly jig?

C-clamps are widely used in aircraft assembly for securing stringers in place on the assembly jig due to their strong, stable grip and ease of use. They have a threaded screw mechanism that allows for precise adjustment of clamping pressure, achieving a secure and uniform hold around the stringers. This functionality is critical in aerospace assembly, where maintaining correct alignment and positioning is essential for structural integrity and safety during the assembly process.

Using C-clamps enables the technician to easily position stringers precisely, ensuring they are well secured while additional assembly operations are carried out. Their design allows them to apply pressure across a broad area without shifting the material, thus minimizing any risk of damage while keeping everything aligned during the assembly process.
