Torque screwdriver set Wiha 38074

Wiha 38074 torque screwdriver set with Pozidriv/PlusMinus slimBits provides a steplessly adjustable torque range for controlled fastening on live parts up to 1,000 V AC. The set includes a VDE torque handle adjustable from 1.0 to 5.0 Nm with a Torque Setter adjusting tool, an insulated metal bit holder for 6 mm slimBits, and individually insulated slimBits tested for 1,000 V AC. Tools are manufactured according to IEC 60900 and meet DIN EN ISO 6789 requirements.

Advantages

The correct torque setting reduces costs by preventing warranty claims and avoiding material damage that would require rework. SlimBits offer protected access to deep-set screws, increasing work safety and efficiency. Each tool is individually tested at 10,000 V AC and approved for use up to 1,000 V AC, providing full insulation protection for electrical work.

Suitable for

• Controlled fastening on live electrical parts up to 1,000 V AC
• Working with deep-set screws using slimBits
• Precision torque applications where 1.0–5.0 Nm is required
• Professional electrical installation and maintenance

How to use

Set the required torque on the VDE torque handle using the supplied Torque Setter adjusting tool. Insert the appropriate slimBit into the insulated bit holder or the adapter as required. Use the tool for controlled fastening, applying torque within the specified range to avoid over-tightening. The insulated bits and holder allow safe work on live parts when used according to the specified voltage rating.

Recommendations

Only use the set for electrical work up to 1,000 V AC as specified. Verify the torque setting before each fastening operation and periodically check insulating integrity. Do not use damaged bits or holders; replace components if insulation is compromised.
