What could excessive torque on aluminum bolts lead to?

Excessive torque on aluminum bolts can lead to breakage or failure due to the material properties of aluminum. Aluminum is softer and more malleable compared to other metals, which means it has a limit to the amount of stress it can withstand before deforming or failing. When bolts are over-torqued, they can stretch beyond their elastic limit, resulting in permanent deformation or even fracturing of the bolt. This can compromise the integrity of the connection being fastened and lead to joint failure.

In contrast, stronger connections, increased durability, and reduced friction are not outcomes associated with excessive torque on aluminum bolts. Properly torqued bolts are designed to provide strength without risking damage, but surpassing the recommended torque values leads to detrimental effects rather than enhancements in performance.
