Turning and marking

The forged steel is turned into the required form and size. Once the turning process has finished,
the products are engraved.

Surface treatment

The hand sockets and accessories are then chrome-plated. The impact sockets are phosphatized, what gives them their distinctive black finish and an additional durable protection against corrosion.

Inspection

Our products are checked periodically at each stage in manufacture. The tools are eventually tested for maximum and minimum tolerances.
