http://www.notchead.com/index.html Something new in the way of fasteners... at least I haven't seen them before.

very pretty, a nice way to gem up a show car, and good for security, would be lost on a grubby engine

And not only do you get high dollar Hardware.... you get to pay an extreme dollar amount for the tools (probably). That 7 notches thing is just for propriety....

Yeah, new fastener designs are not always done for the best of reasons. Sometimes you might get the back story and go... Oh... Ok, I can see what and why that was done that way; makes perfect sense now. But then there is ... WHY !

It's "cause it's Purdy" in this case....

Yeah, I don't think it will make it to the Standards Books either. I have been hearing snippets/rumors that some of the off-shore countries/auto manufactures have been thinking about doing some switching to Whitworth fasteners (http://en.wikipedia.org/wiki/British_Standard_Whitworth http://www.britishfasteners.com/threads/bsw.html http://www.team.net/sol/tech/whitworth-hist.html) I had some Whitworth specific tools at one time but they grew legs and ran for it.

A great quote from one of those hippy-dippy bands the kids are listening to these days sums thos up pretty perfectly "A brand new filling for a brand new hole"
