William:

Have you tried dousing the crevice at the nut / threaded stud interface, with penetrating oil ??

E.g. brand name "liquid wrench".

Repeat application a few times and allow a couple of hours for the penetrating oil to seep into the crevice.

HTH.

Subject: [GTALUG] (very off topic) torque spec of impact wrench

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.
