Why is it important to use proper torque specifications on wheel fasteners?

Using proper torque specifications on wheel fasteners is crucial to prevent mechanical failures. When wheel fasteners, such as lug nuts or bolts, are torqued to the correct specifications, they are properly clamped to the wheel hub, ensuring that the wheel remains securely attached to the vehicle during operation. If the fasteners are over-torqued, they can stretch or even break, leading to potential detachment of the wheel. Conversely, if too little torque is applied, the fasteners may loosen over time, especially under the dynamic forces encountered during driving. This could result in the wheel becoming loose, which can lead to a catastrophic failure, causing loss of control of the vehicle and posing significant safety risks.

While maintaining manufacturer warranty, enhancing vehicle aesthetics, and preventing rust are important considerations, they do not directly relate to the primary function of wheel fasteners in ensuring the safe and reliable operation of a vehicle. Proper torque specifications primarily serve to prevent mechanical failures and to keep the wheels securely attached, which is vital for both operational safety and vehicle performance.
