Can you enlighten us (uh, me) a bit? What's a breaker bar -- is it a sheath-type device you put on the handle-end of the wrench for more leverage? How is that less likely to cause problems -- because the constant, too-weak twisting from a regular wrench might snap the bolt head off?NHPilot said:...when trying to remove a stuck bolt, you're more likely to break the bolt that way. The preferred method would be using a breaker bar which allows you to give a quick twist to get it loose.:4:
You are correct. Torque wrenches have a working range and use as a breaker bar causes them to either exceed their range or use the upper limits. A beam type torque wrench will fracture and fail and the micrometer types will need to be recalibrated if used at the extremes often enough.seadog said:I thought using a torque wrench as a breaker bar was a no-no.
