A torque wrench is a precision tool used to apply a specific amount of torque to a fastener such as a nut or bolt. In cybersecurity contexts, the term may appear metaphorically to describe tools or techniques that apply precise control or force to a digital system, ensuring that components are neither too loose (vulnerable) nor too tight (overly restricted). However, its primary meaning remains in the physical realm, where it is essential for tasks requiring exact tension, such as assembling hardware, securing server racks, or maintaining network infrastructure. Using a torque wrench helps prevent damage from overtightening and ensures reliable, safe connections.
