What can be a consequence of over-torquing?

Over-torquing refers to the application of excessive torque to a bolt or fastener beyond its intended capacity. This can lead to several negative consequences, with one significant outcome being an increased chance of bolt failure. When a bolt is over-torqued, it may exceed its elastic limit, causing permanent deformation or even breaking. Such failure can result from the bolt stretching too far, the threads stripping, or the material cracking due to stress concentration. These failures not only jeopardize the integrity of the assembly but can also pose safety hazards, leading to equipment malfunction or accidents.

In contrast, excessive torque does not improve joint strength, enhance equipment lifespan, or reduce maintenance frequency, as these outcomes are reliant on properly torqued fasteners that maintain their designed performance and mechanical properties.
