Manual screwdriver Wera 05074716001

Wera torque screwdriver model 05074716001 is a factory pre-set precision tool with the smallest scale torque setting. Manufactured in the Czech Republic, the straight manual screwdriver combines a Rapidaptor quick-release bit holder and a multi-component Kraftform handle designed for comfortable, high-speed operation. It accepts 1/4" external hexagon drive bits (DIN ISO 1173-C 6.3 / E 6.3) and provides unlimited loosening torque for freeing stuck screws.

Advantages

The torque is pre-set at the factory to the smallest scale value for consistent, repeatable results. Rapidaptor quick-release technology enables fast bit changes without additional adapters. The multi-component handle has hard and soft zones to support high working speeds while reducing hand strain. The torque setting can be changed with an extra tool within the calibrated measuring range and the set value can be verified using a standard torque tester.

Suitable for

• Assembly tasks requiring a constant, repeatable low torque
• Maintenance and repair work with 1/4" hex bits
• Applications where quick bit changes are needed
• Situations requiring extra loosening torque to free stuck screws

How to use

Fit a compatible 1/4" hex bit into the Rapidaptor quick-release holder and engage it until it locks. Use the screwdriver to apply torque to fasteners; the tool will deliver the pre-set, repeatable torque value. For a different torque within the calibrated range, adjust the setting using the appropriate re-calibration tool (re-calibration kit available under code 05137001001) and verify the new setting with a torque tester. When loosening stuck screws, apply reverse rotation — the tool provides unlimited loosening torque.

Usage recommendations

To maintain accuracy, check the torque setting periodically with a calibrated torque tester after adjustments or regular use. Use bits that meet DIN ISO 1173 specifications and avoid applying side loads that could damage the drive interface or affect torque delivery.
