The SILCA HX-One is a workbench set of precision hex keys and bits that makes a home mechanic's kit look and feel like a pro's. Better tool fit means more feel and confidence, and much less chance of rounding expensive titanium or aluminium fasteners.

Highlights

• S2 steel hex keys: 2, 2.5, 3, 4, 5, 6, 8 and 10 mm
• S2 steel Torx bits: T8, T10, T15, T20, T25 and T30
• S2 steel screwdriver bits: PH1, PH2, SL4 and SL5
• SILCA 17-4 stainless magnetic adapter turns the 6 mm key into a 1/4 in bit driver
• CNC-machined beechwood box with magnetic closure

Tool steel and finish

SILCA uses S2 tool steel, a shock-resistant steel refined for the best balance of strength, hardness, shock resistance and dimensional control. The keys are coated in thin dense chrome, then a high-grip, high-visibility textured red polymer finish for control.

HX-One or HX-Two?

The HX-One is the workbench set: hex keys plus small bits that run off the hex keys via the adapter, in a wooden box. The HX-Two is the on-the-go version, with every tool in key form in a compact holder.

Compatibility & fit

Covers hex fasteners from 2 to 10 mm, T8 to T30 Torx, and Phillips PH1 / PH2 and slotted SL4 / SL5 screws. The bits are driven from the 6 mm key through the included 1/4 in adapter.
