Torque screwdriver wiha TorqueVario-S 36849 adjustable torque range

The wiha TorqueVario-S 36849 adjustable torque range screwdriver is a manually operated tool designed to deliver repeatable and controlled torque for fastening applications. It combines an adjustable torque mechanism with a compact handle for tasks that require consistent tightening without relying on power tools. The tool is intended for assembly, maintenance and repair work where precise torque control reduces the risk of damage to components and ensures reliable joint strength.

Advantages

The adjustable torque mechanism allows precise setting of the desired torque value so each fastener is tightened consistently. The compact ergonomic handle supports comfortable manual operation and improved control during use. The mechanical design eliminates the need for batteries or external power, providing reliable performance in environments where electrical tools are impractical. Built for repeatability, it helps reduce variability between operators and supports quality-controlled processes.

Suitable for

• Electronics assembly and component fastening
• Precision mechanical assembly and small machinery
• Field service and maintenance tasks requiring controlled torque
• Laboratory or bench work where consistent torque repeatability is required

Key specifications

• Adjustable torque range for controlled tightening
• Manual, non-powered torque screwdriver design
• Compact ergonomic handle for manual operation
• Repeatable torque delivery for consistent fastener preload
• Suitable for use with a range of interchangeable bits

How to use

Set the torque value on the adjustment mechanism according to the required specification, insert the appropriate bit for the fastener, position the bit in the fastener head and apply steady manual force until the tool indicates the set torque has been reached. After reaching the preset torque the tool will slip or signal completion according to its mechanical design, preventing further increase in torque. Verify torque settings periodically and recalibrate according to the manufacturer's instructions or your quality procedures.

Usage recommendations

For consistent results, select the correct bit size and type for the fastener, confirm the required torque values from component specifications, and perform periodic checks of the torque setting. Store the tool in a dry, dust-free environment and avoid impacts that could alter calibration.
