What does torque refer to in the context of fasteners?

Torque, in the context of fasteners, refers to the rotational force applied to an object. It is the measure of the tendency of a force to cause rotation about an axis, and when applied to fasteners such as nuts and bolts, it is critical for ensuring that these components are securely fastened. The torque applied helps establish the correct tension within the fastener, which is essential for maintaining the integrity of the assembly and ensuring that it can withstand the operational loads without loosening or failing.

The concept of torque is closely linked to the force needed to apply tension in a fastener, signifying that without the proper amount of torque, the fastener may not create the necessary tension to hold components together effectively. Proper torque not only ensures that joints are tight but also prevents issues like stripping threads or overtightening, which can lead to failure of the fastener or the surrounding material.

This explanation highlights the importance of understanding torque in the maintenance and assembly of aviation structures, making it clear why this option is the correct choice in regards to the context of fasteners.
