The HX-Two set includes:
9x Hex Wrenches in 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10mm
9x Torx® Wrenches in T7, T8, T9, T10, T15, T20, T25, T27 and T30
all fitted neatly into a plastic holder.
The hex keys have a red polymer coating, whilst the Torx have a
grey coating. Both are made from heat treated S2 steel with a
chromed finish. Each wrench has the size and a Silca logo laster
etched into it.
The polymer coating is useful as it gives some resistance to
slippage when you have oily hands, compared to a bare metal finish.
It's more hard wearing than a painted finish, and easier to keep
clean than a rubber coating.
The chromed finish is, in my experience, more durable than the
matt black finish you often see on cheaper tools, and it certainly
feels nicer in the hand.
