Self tapping screws

A couple decades ago, I ran across a handfull of self-tapping screws.They were like sheet metal screws, but with skirted hex heads. Thesewere about 1/2" long and 1/4" dia. I'd seen them used with a specialhead on a drill motor, it having a hex chuck that would ratchet when thescrew bottomed out. What amazed me about these was the fact they wherenot only self-starting AND self-tapping, but they where pretty damnhard. In experimenting, I discovered they tapped and screwed into anold BSA motorcycle frame like it was soft pine.I now find myself in need of something like this and was wondering justwhat, exactly, do I ask for when I go down to the hardware store.nb

I find all sorts of square-drive screws at McFeelys (and have bought quite a few). Star (Torx) drive screws are far superior to even square-drive. They're expensive, though.

oops! I meant to type "self-drilling"... the hex heads with the drill point tip

For self tapping, you need to start early.
