Your favourite screw head

Arran Cameron

What is your favourite screw head for small machine and self tapping screws? Is it Slotted, Pozidriv, Torx, JIS B 1012, or do you prefer something more exotic like Pentalobe or Tri-Wing?

    Depends on the hardness of the material of the screw, if it's a decent steel then hex socket or (for bigger screws) torx, for brass slotted, and for anything in between (which is most screws) pozi. But then I do tend to go for hex when I use stainless screws, which are pretty soft, so it's slightly more subtle than that.


    Torx should be brilliant, but the slight slope on the drivers means they can still tend to cam-out, which hex socket doesn't. It would seem that a "straight sided torx" would be superb, but maybe there's a subtle reason it wouldn't work? (Maybe hard to locate the tool in automated assembly?)


    Or the other answer: whichever I've got most of in the drawer that are the right size!


    And just occasionally I see my absolute favourite even in small screws: hex head. Not beautiful, but can nearly always be undone (because you can get a grip on the blessed things) however old they are.


    Most hated? Probably Philips...you get one shot at undoing them and if you muck that up you're doomed...
