First off they do not lend themselves well to large application. Secondly, you do NOT want them in high heat areas like exhaust.

When a hex head bolt rounds off or otherwise gives trouble there are many things you can do. With a large Torx, once it strips you're (pardon the pun) screwed.

I worked for a while on a large fleet of electric fork trucks of which the manufacturer obviously took advantage of the low cost of Torx fasteners. This was equipment that was heavily abused, so I was digging out broken bolts all too often. I would rather deal with a buggered up hex head bolt or screw rather than a Torx any time.
