Should you double click a torque wrench?

One of the reasons for doing this, though, might be when you are torquing, the fastener itself becomes slightly bound up, not giving a perfectly correct reading.

What advantage does a socket wrench have over a box wrench?

Should you use an impact wrench to tighten lug nuts?

Will a cordless impact wrench remove lug nuts?

You can remove lug nuts of your car using an impact driver provided the nuts are tightened at the right amount of torque (80 to 100lb-ft) and your impact driver’s output torque is higher than 100lb-ft. In practice, however, rusted/frozen and over-torqued lug nuts will not break loose with a cordless impact driver.

Will impact wrench break bolts?

A pneumatic or electric impact gun should be the tool of last resort because it often simply breaks the bolt. Use the proper impact socket, wear gloves and safety glasses.
