Choosing the Right Tool for the Job: Impact Socket vs Torque Wrench

Impact Socket vs Torque Wrench: What's the Best Choice?

When it comes to tightening lug nuts, technicians often have different preferences for the tools they use. In this case, Technician A uses an impact socket on an impact wrench, while Technician B opts for a torque wrench. So, who is using the right tool for the job?

Technician A: To save time and effort, Technician A uses an impact socket on an impact wrench to quickly tighten lug nuts. While this method might seem efficient, it may not provide the accurate torque needed for proper wheel installation.

Technician B: On the other hand, Technician B tightens lug nuts in a criss-cross pattern with a torque wrench. This method ensures that the lug nuts are tightened to the manufacturer's recommended torque specifications, reducing the risk of over-tightening or under-tightening.

Conclusion: Because it is a safer method and complies with industry standards, Technician B, who uses a torque wrench to tighten the lug nuts in a crisscross pattern, is more likely to be right.

Measuring Tools for Runout and Pipe Size

Now, let's talk about the appropriate measuring tools for runout and pipe size:

For Runout: A straightforward height gauge is placed on the reference surface to measure runout. All datum points are fixed, and the central datum axis is rotated to control the datum axis.

For Pipe Size: Vernier callipers are used to precisely measure shorter distances. A precision tool called a vernier calliper is used to measure both internal and external lengths of pipes.

Question:

What measuring tool is appropriate for runout groups of answer options?

Answer:

A height gauge is the appropriate measuring tool for runout groups of answer options.
