Manual screwdriver Wiha 26901 — 119 mm length, precision hand tool

Wiha 26901 is a manual precision screwdriver with a total length of 119 mm designed for controlled, short-reach fastening tasks. The tool features an ergonomic multi-component handle that is particularly light and compact, with handle proportions optimised for precise torque setting. The screwdriver is compatible with all blades of the Wiha 2859 series and is intended for fine mechanical, electronic and general workshop use where recommended torque settings are important.

Advantages

The multi-component ergonomic handle provides a comfortable grip while remaining compact and lightweight for use in confined spaces. A perceptible and audible click indicates when the pre-set torque has been reached, reducing the risk of over-tightening. The tool meets international standards for torque screwdrivers (EN ISO 6798, BS EN 26789, ASME B107.14M) and offers accuracy of ±6% traceable to national standards. It is delivered in a practical plastic box and includes a factory calibration certificate for traceability.

Suitable for

• Fine mechanical assembly and adjustment
• Electronic equipment maintenance and repair
• Precision work in laboratories and calibration workshops
• General workshop tasks requiring controlled torque in short-reach applications

How to use

Select a compatible blade or bit holder from the Wiha 2859 series and insert it into the screwdriver. Set the required pre-set torque value by using the screwdriver's adjustment mechanism or choose a pre-set version if previously configured. Apply steady, even force during tightening; the audible and perceptible click indicates that the pre-set torque has been reached. After use, store the screwdriver in its plastic box to protect calibration and maintain accuracy.

Usage recommendations

Use the Wiha 26901 in combination with torque-interchangeable blades to achieve specified torque values between 0.15 and 8 Nm where applicable. Do not use blades or bit holders that are damaged or worn. For critical applications, verify calibration periodically against national standards; customer-specific pre-set torque values and personalised marking are available via the manufacturer's configurator.
