Wera Click Torque Lock A 5 Torque Wrench

The Wera Click-Torque Lock A 5 is a precision adjustable torque wrench designed for controlled clockwise torque applications, covering a measuring range of 2.5–25 Nm with a ¼" square head drive.

What sets this torque wrench apart is its Torque Lock function, which allows the torque mechanism to be deactivated entirely — enabling the tool to double as a standard ratchet for loosening fasteners. This versatility makes it a practical choice for mechanics, bicycle technicians, and any tradesperson working with smaller fasteners that demand accurate torque control.

Setting the desired torque value is straightforward, with audible and tactile clicks at each scale increment to confirm the setting. Once the target torque is reached during use, a robust release mechanism delivers a clearly perceptible click — both heard and felt — to signal that the correct torque has been applied. The fine-toothed reversible ratchet features 45 teeth for precise operation in confined spaces.

Accuracy is certified at ±4% in accordance with DIN EN ISO 6789-1:2017-07, making this wrench suitable for professional applications where consistent, repeatable torque is essential.
