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?

    It is one thing to  make it tamper-evident, quite another to make something tamper proof.

    The 'edge' that such security as fancy screw heads gives is short lived, as it does not take long for the tool-shape to be copied.

    Even before that point, if you have a good cause and only want to take it out and do not care too much about how, then left hand drill bits, the dremel, and in a few cases just brazing or welding a standard nut onto the top (for shear-head cones) are all techniques known to the workshop...
