Beam torque wrench Wiha TorqueVario-S T electric

The Wiha TorqueVario-S T electric is a fully adjustable torque screwdriver with a T-handle designed for precise fastening between 5 and 14 Nm. It combines an adjustable torque mechanism with insulated torque blades and a clear numerical Nm display, delivering controlled torque application for electrical and mechanical tasks. The tool is VDE- and IEC-certified for safe work on live parts up to 1,000 V AC and meets EN ISO 6789 release accuracy requirements.

Advantages

The torque screwdriver provides an audible and tactile signal when the preset torque is reached and features an integrated friction clutch to prevent exceeding the target torque. Torque settings are adjusted via a side lid accessible with a one-cent coin and set using the supplied adjusting tool. With a release accuracy of ±6% and insulation on the handle and blades, the tool protects both material and the user while reducing follow-up work.

Suitable for

• Precision fastening of screws and bolts within the 5–14 Nm range
• Electrical installation and maintenance on live parts up to 1,000 V AC
• Professional assembly and service work requiring calibrated torque

How to use

Open the side lid with a one-cent coin to access the adjustment mechanism. Use the supplied adjusting tool to set the desired torque value and confirm the setting on the numerical Nm display. Apply the T-handle to the fastener and tighten until the audible and tactile signal indicates the preset torque has been reached. The integrated friction clutch will prevent further torque application beyond the set value.

Recommendations

Verify calibration periodically and follow EN ISO 6789 guidelines for torque tools. Use the insulated torque blades and T-handle only within the specified 5–14 Nm range and on live parts up to 1,000 V AC as certified. Store the tool dry and protect it from mechanical shocks to maintain accuracy.
