What is a radiator tail socket driver?

This socket-type radiator tail driver which fits into a cordless or mains-powered drill can save lots of time.
Many valve tails have integral external nuts moulded or built into them, as shown here. The tail driver is for standard 1/2 inch radiator tails with external hexagonal nuts.
The alternative is to use an open-ended spanner of the right size, or an adjustable spanner.
The valve tail is installed first, using the driver, before the valve is attached to the tail.
Tail drivers are normally made from hardened steel or chromium-vanadium steel - a very hard and durable alloy.
