William, Mechanical designer here. I specify screw torques. Torque is a convenient but not very accurate way to control screw tension. Most of your torque is friction, rather than screw tension. You can try whacking the end of your wrench with a hammer. Maybe this is a good time to see a mechanic. This is what they do for a living.

Hi (another very off topic),
Wheel bolts on my VW are seized pretty hard. Standing on 24in breaker bar doesn't help, and that's 300ft-lb torque. So, I'm thinking about getting an impact wrench. Those with greater than 300ft-lb are very expensive. I found one with 250ft-lb spec at my price range.
Question is, is there difference between static torque vs impact torque? In other words, will 250ft-lb impact wrench loosen 300ft-lb bolt?
Browsing YouTube, I learned that torque specs are always misleading and inflated. This means, I have to find 600ft-lb or greater, and that's serious money. --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
