Incase someone is interested, the names of the security bits are...
but there are pin-in-the-middle torx,
tamperproof torx
pin-in-the-middle hexagon ("Allen"),
something I might call a
tamperproof allen
three-bladed Phillips (like a Phillips but with one
vane removed and
the remaining three vanes at 120? from one another),
tri-wing
"offset" Phillips (like Phillips with each
vane offset to the side by
approximately its own thickness)
torq-set
two-point bits (for which the screw
head is solid with two small holes, one on each side of centre), and
spanner
what I might call "butterfly" bits - I have
no simple unambiguous
name for the shape,
That sounds like a 'clutch bit' as far as I can guess. Does the head
look like an hourglass if viewed appropriately?
