Some years ago, Supascrews were introduced, and mixed packs were sold,

surfaced, and seemed to be the same.

Having stocks of a whole range of sizes (and several drivers), I want to
top up a few, but neither name seems common now. Does anyone know
whether Pozi heads are the same? I don't want to buy, then find the
head of the drive is similar, but not quite the same.
