How should you initiate the installation of a self-locking nut onto a ground stud?

Initiating the installation of a self-locking nut onto a ground stud by hand is the correct approach because it allows for better feel and alignment during the initial threading process. When you start the installation by hand, you can ensure that the threads are correctly aligned and engaged without cross-threading, which could damage both the nut and the stud.

By using your fingers, you can provide the necessary precision to catch the first few threads easily and allow for a smoother installation. This method also enables you to gauge the resistance when tightening, ensuring that the nut is going on straight and can be tightened properly later.

Using a wrench or power tool to start the installation can lead to improper alignment and increase the risk of cross-threading, which can compromise the assembly's integrity. Pliers might not provide the necessary torque control and can also risk damaging the fastener or the ground stud by not evenly distributing the force.
