| I was going through a box of tools I picked up at an auction for a buck for the box. In an old red case I found a lightly used 3/8 inch drive torque wrench. I use claw foot wrenchs for my barrel nuts. They are 1/2" drive. If I use a 3/8 to 1/2 adapter and the 1/2 drive claw foot on the 3/8 wrench, does it change the torque setting?...Is 60lbs setting on the wrench still 60lbs on the wrench? |

Lots of good information on this website about different scenarios concerning torque wrenches and adapters. http://www.engineersedge.com/manufacturing_spec/torque_wrench_2.htm |
| Thanks. I appreciate the reference. I think I understand the part that page took me to. To overcome the extension issue, moving the crow foot to a 90 degree angle with the wrench brings it in line and will overcomes the extension effectI believe , but I still am not sure about the drive going from 3/8" to 1/2" and my math isn't good enough to know how to account for it. |

I've rebarreled many uppers using a Craftsman 3/8" torque wrench and 3/8" to 1/2" adapter, as mentioned, it will be within a pound or two difference (or right on spec). I've used a 1/2" Craftsman torque wrench and verified this in the past.
Main thing is that it is calibrated and that you should always turn the torque setting to the STOP point on the wrench or always wind it down to the minimum scale setting and never to zero when you are done with it(if it's an adjustable click type). |
