I have a Evercraft (NAPA) torgue wrench with adjustments from 10 to 150 ft lbs. It works ok at higher settings like 50 lbs and up. but a lower settings it doesn't seem to click at the setting. Am I doing something wrong? |

At the lighter settings you won't get an audible click, but you should be able to feel it. Just have to apply the torque in a slow, controlled fashion or it is easy to miss. If you have the space, adding a long extension makes the click more obvious at low settings. |

| I don't believe in using the same torque wrench for all ranges. I keep a torque wrench that goes up to 150lbs, and one that only goes up 75lbs for small jobs. As a former crew chief, I've seen too many torque wrenches that just aren't accurate at low values when they can go up to much higher values. |

If you're using low torque settings often, you may want to look into getting another smaller torque wrench. For the longest time I just used a cheap Harbor Freight 1/2" torque wrench (for wheel lugs, brake caliber bolts, etc.) but when I did some major engine work on my car I decided to invest in a good 3/8" GearWrench torque wrench. The 3/8 has a lower torque range but also clicks at much lower torque settings. Now it is my main go-to torque wrench as it will make a nice loud snap at the ~40 lb ft range for caliper bolts where the HF one was purely tactile at that torque level. |

I always understood it as it's top 80% range. I got calibration papers with torque wrenches that don't even test the bottom 20%. Quoted:

I was ways taught that the accurate reading range of a torque wrench is between 25%-75% of its range. I always understood it as it's top 80% range. I got calibration papers with torque wrenches that don't even test the bottom 20%. Snap-On, Mac, and Matco dealers, all told me this when I was looking at quarter drive in/lb tools. They said disregard the range and look at the max, figure 20% and disregard anything below it. I told them I wasn't buying two wrenches and they lost sales, until Mac came out with a perfect one that maxed just over my high target and which put my low in range. If you must use what you have, it will be vague feeling when it clicks at low settings, it will be barely audible, but quite visible, and not horribly accurate. |

Ftlbs is ftlbs. |

Extensions do cause a different reading, read up on it. No they don't. If I put 100 ftlbs on one end of a shaft, the other end is getting 100ftlbs as well. Impact wrench applications excepted. Now offset extensions like a crows foot are a different matter entirely. |
