You need a No.3 square drive bit.
Sachys Robertson and Timbecon have them listed, 50 and 75mm long.
You might also find them at a trade tool supplier, but not at the local hardware store.

The No3 Square Drive bit is only 3.5mm across the flats.
I have been looking for a 4.5mm .... so far with no luck.

Absolutely right, Elraco.
The No.3 I have tapers from 3.5 to 3.9 sq then steps up to 4.4 sq. Sorry about the misinformation, only took one measurement originally.
