I have just had an email from MachineMart and they had admitted they got it wrong. Their 'Flat Drive' sockets are in fact standard Bi-Hex or twelve point, rather than 'Flat Drive' and have invited me to return them for refund. They say the catalogue description is wrong, the cardboard sleeve on the sockets is wrong, yet the photos on both if examined closely do show bi-hex.
Well if you want 12 point flank drive then Gedore, Facom & snapon all still do them.
although there are only a tiny handful of applications that actually need bi-hex, so I would always say to go for single hex impact sockets, they are good for almost every occasion.

I'm waiting for news on the flay drive sockets.
Do they involve a slave & a whip?
I tend to work on no car related stuff where the wall thickness often stitches you up.
This is about car maintenance :) and wall thickness on good quality impact sockets with 3/8 drive is the same as a cheap non impact sockets. It is incredibly rare to find something on a car where an impact socket doesn't go. (apart from really tiny stuff, 8mm and below, which is not really common maintenance territory on a car) For most stuff: brakes, clutches, exhausts, suspension, wheels and the like I use snap on flexible impact sockets in half inch drive with a hefty impact wrench, most under bonnet maintenance stuff like cambelts, alternators etc is 3/8 drive impact deep sockets, but with either an air ratchet or a hand ratchet. When I worked on motorcycles: mostly a 3/8 drive impact wrench plus 3/8 drive sockets.
