Screwdriver bit King Tony 203720 — interchangeable hand tool tip, steel construction

King Tony 203720 is an interchangeable screwdriver bit designed as a replaceable tip for hand and power bit holders. Made from silicon-alloy S2 steel and finished with a polished chrome plating, this bit is intended for driving tamper‑resistant Torx screw heads in general fastening and repair tasks. The bit meets DIN 3120 dimensional standards and is compatible with standard bit holders, adapters and cordless drivers used in workshop and field service environments.

Advantages

The S2 silicon alloy steel construction provides high hardness and wear resistance while the polished chrome plating improves corrosion resistance and facilitates cleaning after use. The detachable design allows quick replacement in multi‑bit drivers and reduces downtime when switching between screw types. Conformance to DIN 3120 ensures dimensional accuracy and reliable fit with compatible Torx tamper‑resistant fasteners.
