Manual screwdriver set Wiha 29234

The Wiha 29234 manual screwdriver set contains a TorqueVario®-S Tplus torque T-handle screwdriver with adjustable torque, adapters, a bit holder and six single bits, all stored in a robust organised box. The torque screwdriver is designed for precision fastening where torque values above 5 Nm are required and for applications that demand repeatable, process-safe tightening.

Advantages

The integrated numeric scale and supplied adjusting tool allow variable torque settings, covering a wide range of applications. A clearly audible and tactile signal is emitted when the set torque is reached, and an internal friction clutch prevents exceeding the required torque. The release accuracy of ±6% meets EN ISO 6789 requirements. The T-handle with soft zones ensures comfortable, efficient torque transmission. The set includes 1/4" and 3/8" internal square adapter blades, a bit holder and six single bits, and is compatible with Wiha interchangeable blades for T-handle torque screwdrivers (series 2899).

Suitable for

• Precision assembly and fastening tasks requiring controlled torque
• Electronics and small mechanical assemblies
• Maintenance and repair work where repeatable torque is needed
• Applications requiring documented or process-safe tightening above 5 Nm

How to use

Select the desired torque value using the integrated numeric scale and adjust it with the supplied adjusting tool. Fit the required adapter or bit into the T-handle, position the screw, and apply steady force. Continue turning until the audible and tactile release signal indicates the preset torque has been reached; the friction clutch prevents further torque. Store the tool and accessories in the supplied box after use.

Usage recommendations

For process-safe results, verify the set torque value before starting critical assemblies and periodically recalibrate according to EN ISO 6789 if used frequently. Use the appropriate adapter or bit size to avoid damage to fasteners and follow component manufacturer torque specifications.
