Working on the premise that there is always at least one screw on every job that is almost unreachable, here is a really good flexible drive shaft, 260mm long, with a spirally wound steel shaft which easily bends up to 90°. It has a 1/4" hex female at one end and a 1/4" hex male at the other and a free running collar just behind the business end. We have yet to see anything better.

Extremely poor build qualityBought this at special offer price but the very first time I used it, it fell apart! Even at a few pence this is still a total waste of money. If an item is sub-standard it should be withdrawn from sale, not offered at a discount.
