Ever see a hammer bounce? (and a tech question)

[MK1Scirocco16v at comcast.net (Dave Ewing)]

If you don't want to go through the hassle of cutting the head off try this.

Pound a torx into the head of the bolt AND use the vice grips at the same
time.  It will come out.  For the last one, use the torx and turn the TB at
the same time (in the off direction).  It will also come off.

In the future, before you try to take the bolts out, give them a few taps,
either directly or through the ext. and bit.  This will not only push the
bit farther into the head of the bolt but also jolt the bolt to loosen up
any rust (or in this case, corrosion) that may be keeping it from loosening
easily.  Using these techniques I have never had to cut the heads off of any
bolts or tap any.  HTH!
