Which tool is employed to install a pre-installed ground stud?

A special pulling tool is used to install a pre-installed ground stud because it is specifically designed to securely attach the ground stud to the aircraft structure. Ground studs are critical for providing a reliable electrical connection and grounding, and the pulling tool ensures that the stud is inserted with the proper force and angle, preventing potential damage to surrounding materials or the grounding stud itself.

Using a specialized tool helps achieve the necessary torque and prevents issues such as cross-threading or incorrect installation, which could result in poor electrical connectivity or failure of the grounding system. This attention to detail is essential in aerospace assembly mechanics, where safety and reliability are paramount.

In comparison, standard wrenches, socket drivers, and impact drivers may not provide the precision or control needed for effectively installing a ground stud, thereby making the special pulling tool the most appropriate choice for this specific task.
