Chave dinamométrica mecânica Wera 05075870001 0,4 - 2 N⋅m

The Wera 05075870001 mechanical torque wrench provides precise, repeatable torque application within a range of 0.4 to 2 N·m. Designed for fine mechanical assembly and maintenance tasks, this compact torque wrench offers a clear scale and a robust metal construction that supports consistent tightening of small fasteners. Its mechanical adjustment and positive click-off feedback help ensure torque accuracy without reliance on batteries or electronics.

Advantages

The wrench combines a narrow torque range with tactile click feedback for reliable control when working with sensitive components. Its mechanical design ensures long-term stability and low-maintenance operation, while a clear, graduated scale enables quick setting and verification of the target torque value. The compact form factor allows access to confined spaces commonly encountered in electronics, optics, and precision engineering.

Suitable for

• Assembly and service of electronic devices and circuit boards
• Precision mechanical assembly such as watches, instruments, and small gearboxes
• Optical equipment adjustment and maintenance
• Laboratory and research equipment requiring controlled fastening

Key specifications

• Torque range: 0.4 – 2 N·m
• Type: mechanical click-type torque wrench
• Drive size: suitable for small sockets and bit adapters (compact drive)
• Adjustment: manual, with graduated scale for direct setting
• Feedback: audible and tactile click at set torque
• Construction: metal body designed for repeated use
• Intended use: low-torque precision fastening

How to use

Select the appropriate bit or socket and attach it to the drive interface. Rotate the adjustment mechanism to set the desired torque value, reading the graduated scale to confirm the setting between 0.4 and 2 N·m. Apply steady force to the handle during tightening; when the preset torque is reached the wrench emits a clear click and a tactile release indicating the correct torque has been achieved. After use, return the adjustment to the lowest setting to reduce stress on the internal spring and store the tool in a dry environment.

Recommendations

Use the wrench within its specified torque range and avoid applying force beyond the upper limit. Do not use the tool for loosening fasteners at torque levels higher than the set value. Periodically verify calibration if used in critical applications and follow manufacturer guidance for maintenance and calibration intervals.
