Hi all thought I'd share this with you all as I purchased a set today and I can't beleave how brilliant it is http://m.screwfix.com/p/nut-socket-driver-bit-set-3pc/17228 This is a socket driver bit for your drill or impact driver ( what I used ) and you attach your socket and off you go, for thoes of us who have struggled to get bolts undone with a ratchet due to lack of leverage or has seized in place, this is heaven most people can't afford an air compressor and air gun this is the next best thing It cost a hole £4 !!!!!!! Hope this helps you all out James
