Impact Wrench and Lug Fastener Safety Guidelines

What should you consider when tightening lug fasteners with an impact wrench?

a. Always use an impact wrench
b. Never use an impact wrench
c. Use in difficult-to-access positions
d. Use in high torque settings

Answer:

An impact wrench should never be used in high torque settings when tightening lug fasteners. Option B is the correct answer.

When tightening lug fasteners, using an impact wrench in high torque settings can lead to overtightening of the lug nuts and potential damage to the wheel assembly. It is important to use caution and follow proper safety guidelines to prevent such issues.

Instead of using an impact wrench, a torque wrench should be utilized for precise tightening according to the recommended torque specification provided by the vehicle manufacturer. This ensures that the lug fasteners are properly secured without the risk of overtightening.

While an impact wrench may be suitable for use in difficult-to-access positions where a torque wrench cannot fit, it is crucial to remain vigilant and avoid excessive torque settings to prevent damage.

Following these safety guidelines when using an impact wrench for lug fasteners will help maintain the integrity and safety of the wheel assembly.
