What happens when you exceed the desired torque in using a torque wrench?

When torque is applied beyond the desired level using a torque wrench, it can lead to the fastener being overstressed. This excess torque can cause a range of detrimental effects, including the potential for breaking the fastener. Fasteners are designed to withstand specific torque levels to ensure they maintain their integrity and performance; exceeding this threshold can result in material fatigue, stripping of threads, or even snapping the fastener entirely. This is why it is crucial to always use a torque wrench according to the manufacturer’s specifications and ensure that the correct settings are applied to avoid structural failure in aviation applications.
