Torque screwdriver Wiha TorqueVario-S ESD 43898, adjustable torque 0.8–2.5 Nm, anti-static

The Wiha TorqueVario-S ESD torque screwdriver offers adjustable torque from 0.8 to 2.5 Nm in an anti‑static design intended for use on sensitive electronic assemblies. The tool provides repeatable, preset torque control to ensure consistent fastening without relying on power drivers. Its compact, ergonomic body and ESD‑safe materials make it suitable for precise assembly and maintenance tasks in electronics, instrumentation and fine mechanical applications.

Advantages

The adjustable torque range of 0.8–2.5 Nm enables controlled tightening of small fasteners while preventing over‑ or under‑torquing. ESD‑safe construction reduces the risk of electrostatic discharge when working with circuit boards and other sensitive components. The screwdriver delivers repeatable torque settings for consistent results across multiple fastenings, and its compact form factor improves access in confined spaces common in electronic enclosures and instrumentation.

How to use

Set the required torque value within the 0.8–2.5 Nm range following the scale or adjustment mechanism on the tool. Fit the appropriate bit to match the fastener head and place the screwdriver on the screw. Apply steady pressure and turn until the mechanism signals that the preset torque has been reached; then stop rotating to maintain the set torque. For repeatable tightening, verify the setting before each sequence and periodically check the tool calibration according to workplace quality procedures.

Recommendations

Use the torque screwdriver in an ESD‑controlled workspace and pair it with properly specified bits sized to the fasteners. Avoid using the tool for applications exceeding its torque range and follow regular calibration intervals to preserve accuracy.
