That's great Anthony, so long as the slot in the screw is not already worn as a result of current or previous owners using poorly fitting and often smaller screwdrivers than are optimum for the job. Looking through various tool shops at the screwdrivers that are available, and many shops only keep in stock those tools that sell easily and quickly with the result that what you want for this specific job is rarely available. The exception is one of the tool bits that are supplied with many impact drivers, and which is big enough to fit the drain plug properly, and which may fit into a half inch or other suitably sized ratchet spanner. Otherwise, yes I agree.
