Brand: Wiha

Availability set by the retailer

The Wiha SoftFinish TorqueVario-S is an adjustable torque screwdriver handle engineered for precision fastening in production, assembly, electronics, electrical, and maintenance applications where exact torque control is essential. The Newton meter scale model covers an adjustable torque range of 0.8 to 5.0 Nm in fine 0.20 Nm increments, set quickly and accurately using the included torque setting adjustment tool. A laser-calibrated, clearly marked display scale shows the exact torque setting at a glance, and each tool is serialized with a serial number and ships with a certificate of calibration for full traceability. When the preset torque is reached, the driver emits a distinctly audible and perceptible click and automatically resets for the next torque cycle, preventing over-torque and ensuring repeatable, consistent results. Accuracy is guaranteed to +/-6% tolerance for 5,000 cycles or one year, meeting ASME B107.14m, EN ISO 6789, and BS EN 26789 standards. The enclosed mechanism is ideal for production-controlled environments, keeping the internal calibration clean and protected. The ergonomic SoftFinish cushion grip handle provides comfortable, secure control during extended use, and the included 1/4-inch bit holder adapter lets you pair the handle with Wiha TorqueControl blades or standard 1/4-inch hex bits for a wide variety of fastening tasks. Designed and manufactured in Germany, the TorqueVario-S is backed by Wiha's No Hassle Guarantee.

Choosing Drivers

How do I choose a screwdriver?

Match the tip to the fastener recess exactly, choose a handle that fills your hand for torque, and pick a shank length that reaches the fastener without bottoming out. For electrical work, insulated handles rated to a recognized standard add a safety margin. A set covering common tip types covers most jobs.
