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.

I suppose.....but why is a Torx bolt any cheaper than a hex/allen bolt?

They're more expensive.

There were some applications where I spec'ed them, because they made sense, and purchasing would call me and ask if they could substitute cheaper Phillips et al.

They are GREAT for manufacturing, less great when they're rusty and cruddy.

It sounds like this is one of those areas where my age has been detected.

In the beginning, like in the seventies, the word was that Torx fasteners were available dirt cheap to manufacturers so that they could sell the tools. Now that some 30 years or more has passed by, now that they are more widely used, they can get more for them.

Don't get me wrong there are certain SMALL size applications where I like them, but for the most part, I would be just fine if they had never been invented.

Pretty much how I feel about them too.
