Which tool is used to install a direct ground stud?

The use of a nutrunner is essential for installing a direct ground stud due to its ability to provide the correct torque settings necessary for ensuring a secure and reliable electrical connection. A nutrunner, often powered, allows for precise control over the amount of torque applied, which is crucial in preventing damage to both the stud and the materials being connected. This helps to ensure that the grounding connection maintains its integrity over time, which is vital for the safety and performance of aerospace components.

In contrast, while a screwdriver might be useful for fastening smaller components, it is not suited for the demands of grounding studs, which require more robust torque. Pliers can grip and hold fasteners but do not offer the controlled torque application necessary for secure installations. A socket wrench is useful but typically does not provide the same level of control or ease of use as a nutrunner when it comes to achieving specific torque settings efficiently. Thus, the nutrunner is the best tool for installing a direct ground stud effectively and safely.
