I've been asked to attach some fixings to steel sheet using hexagonal-
headed TEKS screws (as already used for similar fixings in the same
location). These, apparently are self tapping - but do they need a pilot
hole? If not, how do I start them off? Are they meant to be driven by a
spanner, or a power tool?

The ones I used roofing one of my buildings in steel profile sheeting
just sat in a hex socket in my Wickes bat op drill, and with an
initial stout push went in nicely. They had a cutting edge ground on
the point, and the screw bit only started after maybe a mm or so.

If they are what I'm thinking of they have a 'drill' on the tip of the
screw so are truly a one shot approach to fixing into sheet metal. A drill
with a suitable socket on the end is all you need - although a centre
punch helps if you need accurate spacing, etc.

Thanks to both who replied - that did the trick.
