Overview
The Fujiya KUROKIN Through-Tang Strike Cap Screwdriver is designed for installation, maintenance, and general service work where screws are rusted, seized, or stripped. The steel shaft runs through the handle to a large gold-plated strike nut, so hammer blows go straight to the tip to help break loose stubborn fasteners.
The compact 3.9" (100 mm) Si-Cr-V steel shaft keeps it easy to control in tight spaces, and the large 1.6" (40 mm) cushion grip supports strong torque and comfortable repeated use. A magnetized black point tip helps hold screws during placement. Available in Phillips (+2) and Slotted (-6). Made in Japan.
Important: This is not a voltage-rated insulated screwdriver. It is not certified to IEC 60900 / VDE 1000V and is not intended for use on energized circuits. Always disconnect power and verify the circuit is de-energized with a tester before use. Fujiya notes that if the ceramic section is damaged or moisture enters the tool, electrical conduction may occur.

Product Safety
- Always wear appropriate personal protective equipment (PPE), such as gloves and safety glasses, when using tools.
- Wear safety glasses when striking, cutting, or prying with any tool.
- Inspect each tool before use and do not operate if damaged.
- Use all tools only for their intended purpose and within their specified limits.
- Do not use on live electrical circuits unless the tool is certified to IEC 60900 / VDE 1000V and marked accordingly.
- Only tools carrying that certification are rated for work near energized conductors.
- A plastic handle, resin shaft cover, or internal insulating component is not electrical insulation and will not protect you from shock.
- Always disconnect power and verify the circuit is de-energized with a tester before working on electrical equipment.
- Store tools in a dry location and keep them out of reach of children.
