Ideal for...

This torque wrench is the right choice for auto mechanics, bicycle mechanics, electricians, and anyone who needs defined tightening torques. Thanks to its compact design and light weight of only 0.76 kg, it is also well suited for mobile use.

How to use the BETA 666/5

Set the desired torque on the handle until the scale shows the required value. Tighten the screw with a steady motion until a distinct click is heard – the torque has been reached. After use, turn the wrench back to the lowest value to release the spring and extend its service life.
