Wera 05074717001 Adjustable Torque Screwdriver 3.0-6.0 Nm, 1/4 inch Hex Rapidaptor, VDE Insulated, 155 mm

For electricians and maintenance technicians who demand repeatable precision on sensitive connections, the Wera 05074717001 adjustable torque screwdriver eliminates guesswork with a continuously adjustable 3.0–6.0 Nm range and a clear scale. Unlike fixed-torque tools, this Kraftform driver lets you dial in the exact setting for each job, then delivers an audible and perceptible click when the target torque is reached. The VDE insulation and IEC 60900:2018 certification make it safe for live working up to 1000 V AC, while the Rapidaptor quick-release chuck accepts standard 1/4" hex bits for fast changes.

Highlights

• Adjustable torque from 3.0 to 6.0 Nm, calibrated to ±6 % per DIN EN ISO 6789-1:2017
• VDE insulated handle and blade, tested to 10,000 V and certified for 1000 V AC / 1500 V DC
• Rapidaptor quick-release chuck for one-handed bit insertion and removal
• Audible and tactile click signals correct torque; unlimited loosening torque for stuck screws
• Ergonomic Kraftform multi-component handle reduces hand fatigue during repetitive work
• Integrated adjustment tool and individual test certificate included

In daily use

Set the desired torque by rotating the handle end and reading the scale, then insert a 1/4" hex bit into the Rapidaptor chuck. The screwdriver tightens clockwise until the preset value is reached, at which point the mechanism disengages with a clear click—preventing over-tightening of terminals, circuit breakers, and electronic components. For loosening, the torque limiter is bypassed, so you can apply full force without damaging the tool. The 155 mm overall length provides good control in distribution boards and confined spaces.
