Overtight

Overtight refers to the act of applying excessive force when fastening a component, such as a screw, bolt, or nut. This can lead to a variety of negative consequences depending on the materials involved and the specific application. In metal components, overtightening can strip threads, causing the fastener to lose its grip or become permanently stuck. It can also deform or crack the materials being joined, leading to structural weakness or failure.

In plastic components, overtightening is particularly problematic as plastics are generally less strong and more brittle than metals. This can easily result in the plastic cracking, breaking, or the threads within the plastic being stripped. For delicate electronics, overtightening can damage sensitive components or the circuit board itself. Even in seemingly robust applications like automotive parts, overtightening can warp metal surfaces, create stress points, or lead to premature wear.

The appropriate torque, or rotational force, for a fastener is usually specified by the manufacturer. Using a torque wrench is the most accurate way to ensure a fastener is tightened correctly, avoiding both overtightening and undertightening. Undertightening can lead to components loosening over time, while overtightening causes the damage described above. Proper tightening is crucial for the longevity, safety, and performance of assembled products.
