Single screwdriver Wiha 322

The Single screwdriver Wiha 322 is a 243 mm insulated hand tool designed for precise work on external hex screws and hex nuts. It combines a chrome-vanadium steel blade with a black finish and direct-moulded insulation on the blade, and an ergonomic Wiha SoftFinish® multi-component handle with roll-off protection. Manufactured according to IEC 60900:2012 and DIN 3125, this model is intended for applications that require electrical insulation and controlled torque transfer in manual fastening tasks.

Advantages

The blade is made of through-hardened chrome-vanadium steel with a protective black finish, offering durability and resistance to wear. Insulation is moulded directly onto the blade to provide safe handling where insulated tools are required. The ergonomic SoftFinish® handle supports comfortable, fatigue-reducing grip and precise control, while roll-off protection prevents the tool from rolling away on work surfaces. Compliance with IEC 60900:2012 ensures the tool meets relevant safety standards for insulated hand tools.

How to use

Select the Wiha 322 screwdriver matching the size of the external hex screw or nut. Insert the deep-drawn socket onto the fastener and apply steady, controlled force while maintaining a comfortable grip on the SoftFinish® handle. For insulated applications, ensure the insulation on the blade remains intact and free from damage before use. Avoid using the tool for prying or striking, and keep the blade and handle clean to preserve function and safety.

Recommendations

Inspect the insulation before each use and replace the screwdriver if the moulded insulation shows cuts, cracks, or other damage. Use the tool only within the rated insulation limits and follow local safety procedures when working on or near live electrical components.
