Which tool is specifically designed to remove Hi-Lok collars from an assembly?

The tool designed specifically to remove Hi-Lok collars from an assembly is Hi-Lok collar pliers. These pliers are engineered to grasp and manipulate the unique shape of Hi-Lok collars effectively, allowing the mechanic to disengage them without damaging the surrounding components or the collar itself. The design of Hi-Lok collar pliers offers the precision and leverage needed to facilitate the removal process, making it a specialized tool tailored for this particular task.

Other tools, such as rivet guns, standard pliers, and vice grips, are not intended for this specific application. Rivet guns are used for installing rivets rather than removing them, whereas standard pliers and vice grips offer general gripping but lack the specific features necessary to handle Hi-Lok collars safely and effectively. Using the correct tool is crucial in aerospace assembly to ensure that parts are not damaged and that assembly standards are maintained.
