Manual screwdriver Wera 05074717001 — 150 mm length, torque 3–6 Nm compatible

Wera 05074717001 is a manual torque screwdriver with a 150 mm shaft designed for precise screwdriving where a consistent torque is required. It features a pistol-style multi-component Kraftform handle for efficient transmission of higher torque and comfortable operation at higher working speeds. The tool is factory-set to the lowest torque scale value and allows adjustable torque within its measuring range using a separate tool; set values can be verified with a standard torque tester. Rapidaptor quick-release technology enables fast bit changes, and the screwdriver provides unlimited loosening torque for releasing seized fasteners.

Advantages

The Kraftform pistol handle combines hard and soft zones to improve grip comfort and torque transfer. Factory pre-set torque ensures repeatable tightening at the smallest scale value, while the mechanism can be adjusted with an additional tool to change the torque setting. Rapidaptor quick-release system speeds up bit changes and the 1/4" hex drive compatibility makes the screwdriver suitable for common interchange bits. The design allows unlimited loosening torque so stuck screws can be slackened without damaging the torque mechanism.

Suitable for

• Assembly and maintenance tasks requiring controlled torque (electronics, small machinery)
• Service jobs where repeatable torque values are needed
• Workflows that use 1/4" hex bits and demand quick bit changes
• Situations where occasional high loosening torque is needed

When it may not be suitable

This torque screwdriver is pre-set at the factory to the smallest scale value and is intended for torque-controlled manual fastening within its measuring range (3–6 Nm). It is not suitable for applications that require torque values outside the specified range or for high-volume automated tightening where powered tools are necessary. If frequent re-calibration or a very different torque range is required, consider a tool specifically rated for that range or a powered torque-controlled solution.

Key specifications

• Shaft length: 150 mm (approximate overall length 155 mm)
• Torque range: 3–6 Nm (factory pre-set to the smallest scale value)
• Drive type: 1/4" external hexagon drive (compatible with DIN ISO 1173 C 6.3 / E 6.3 bits)
• Handle: Multi-component Kraftform pistol handle with hard and soft zones
• Bit change: Rapidaptor quick-release technology for rapid bit changes
• Loosening torque: Unlimited (allows slackening of stuck screws)

How to use

Select a compatible 1/4" hex bit and insert it into the Rapidaptor quick-release chuck. Use the pistol-style Kraftform handle to apply manual torque until the preset torque setting is reached; the screwdriver will slip or indicate when the set value is achieved. If you need a different torque within the tool's measuring range, adjust the setting using the separate adjustment tool or order the recommended re-calibration kit and then verify the value with an off-the-shelf torque tester. For loosening, use the tool normally — the mechanism allows unlimited loosening torque to break free seized fasteners.

What to consider before purchase

• Required torque range — this model works within 3–6 Nm; confirm this matches your tasks
• Compatibility with 1/4" hex bits and existing bit sets
• Need for adjustable or different torque ranges and availability of a re-calibration kit
• Whether manual operation and pistol-style grip suit your workflow compared to powered tools

Usage recommendations

Use appropriate 1/4" bits and verify torque settings with a torque tester after any adjustment. For repeatable results, keep the tool clean and avoid impacts that could affect calibration; order the re-calibration kit if precise adjustments or checks are required.
