What is the specific bolt that torque must be installed on immediately after installation?

The correct answer is the 10th bolt, as it is crucial in ensuring the integrity and security of the overall assembly during installation. The purpose of torquing bolts is to create a specific amount of tension that allows the components being fastened to work together effectively. By focusing on the 10th bolt immediately after installation, one provides a critical point in the assembly sequence that can prevent issues such as bolt loosening or failure during the operational phase.

This practice is common in situations where consistent torque is necessary to maintain balance and safety in structures, machinery, or equipment. The methodology typically emphasizes that the initial bolts be tightened to a specification followed by the 10th, as this is where adjustments can make a significant impact on further installations and the resultant load distribution across the assembly.

Understanding this helps ensure that the assembly remains tight and prevents any potential catastrophic failures that can arise from improperly torqued hardware.
