Over-torquing fasteners, such as bolts and nuts, can lead to several problems and is generally not recommended. Here are some reasons why you shouldn't over-torque fasteners:

There is a tendency we have is to tighten fasteners as much as possible to ensure a secure installation, but this doesn't always produce the best results. In some cases, over-tightening screws can even do more harm than good.

Thread Stripping: Over-tightening can cause the threads on the fastener or the hole to strip, which can lead to a weakened connection or even failure.

Bolt Failure: Excessive torque can cause the fastener to stretch beyond its yield strength, leading to permanent deformation or even breakage.

Component Damage: Over-torquing can lead to damage to the components being fastened, such as cracking or warping, especially if they are made of brittle materials.

Reduced Fatigue Life: Bolts subjected to over-torquing can experience increased stress, which can reduce their fatigue life and make them more susceptible to failure under cyclic loading.

Gasket Damage: If a fastener is used with a gasket, over-torquing can cause the gasket to be crushed, leading to leaks or failure to seal effectively.

Increased Stress on Joints: Over-tightening can increase the stress on the joint, potentially leading to joint failure or increased wear and tear.

Difficulty in Removal: Over-tightened fasteners can be difficult to remove, especially if the threads have stripped or the fastener has seized.

Reduced Reliability: Over-torquing can reduce the reliability of the fastened joint, as it can lead to a variety of issues that compromise the integrity of the connection.
