I have had an idea.

Short hex-headed screwdriver bits are widely available and used, with relatively long handles. One should be able to obtain a "handle" of approximately zero length, in the form of a knurled disc with a hexagonal axial hole not quite through it. But I don't recall ever seeing such - a business opportunity?

Have been discussed here before, search for combinations of words from
(hex, palm, finger, ratchet, spinner, disc)

Cheap 1/4 inch socket sets often have a similar part. A round flat piece
of plastic with fine serrated edge and a 1/4 square hole in the middle
to fit the drive shaft of the socket.

Probably completely useless unless the bolt is only finger tight. For a
screwdriver you need something that fits easily in the hand and not just
two fingers.

I have a set with that disc made of metal. It's only real use is to run
the screw/nut/bolt fast when there is nothing to resist it.
Recently, it fell on the floor, I must look for it sometime.

I have one of these:
http://www.mountztorque.com/products...driver-bit-set
which is more use as it works for things tighter than would be
doable with a small disc. (I know nothing about that website; it
was just the first hit when I searched for the name of the driver)

Various responses :-

CB: I didn't *mean* something like that, though in the case in question one of those would have served. I meant something simpler and shorter - and cheaper.

alan_m: The screw in question was a pattress screw, *possibly* M3 or 5BA. The screw was undone with my unusually short small screwdriver probably held between a Part P electrician's finger and thumb; it seems likely that a 4 cm disc would have given ample torque held between finger and thumb.

Graham: A slot in the back is an *excellent* idea.

Jon Fairbairn: I have something similar, by Rolson, but thicker at the business end. The smaller of those bits, in that ratchet, would have served. But, when need arose, it was elsewhere.

Fx: testing - I have a newish Rolson ratchet set with ten bits in a black rubbery holder strip, which holds them quite firmly. It holds so firmly that the 5mm bit, held only by the rubber, today easily undid a pattress screw which had not, I think, been turned in the last 34 years.

Thanks to all.

needs to be pozi, not slotted. But since it costs & is rarely used... you're better off without.

I have (nearly) such a thing in my tool bag - it also has a right angle
ratchet handle, so you can use bits in confined spaces by turning the
knurled disc or using the ratchet.

A bit like:

In my set the disc can be set between the head of the ratchet and the socket. It can be usefully used to apply resistance to the socket on a nut which is too loose to resist the action of backing the ratchet handle, or to quickly run up the nut to a point where the ratchet will function.

In *really* tight spaces I sometimes use a ring spanner direct onto the
hex of the bit. Works ok, but you also need some means of pushing down
on the bit to keep it in contact with the screw.

handle, or to quickly run up the nut to a point where the ratchet

My one can't do that, the socket sits too close to the business part of
the ratchet. Nice idea, though.

But I also once had a self-setting nut runner, which had gently
spring-loaded teeth, which clamped bolt or nut perfectly when you
pressed down on the end of the handle. The harder you pushed, the
tighter the grip. Then it got stolen, and I never found its like again.
I was sure it was a Stanley, but they denied all knowledge of it.

And conversely, the bits should have a slot cut into the back, so
a thin flat-bladed screwdriver can turn it to undo screws in deep
receses with no clearance for a normal extention.
