Description:

The spanner is made of chrome vanadium steel, which ensures its durability and strength. It has a mechanical tension of a dynamometric ratchet that jumps one step after reaching the desired tightening force and produces a characteristic noise. 
The torque scale is located in the handle of the spanner, its adjustment is made by turning it.
 After you have set the desired torque, lock the spanner with a safety lock at the end of the handle.

- Material: chrome vanadium steel 

Purpose / application
It is mainly used in automotive engineering for precise fastening and wherever the manufacturer has specified the required tightening torque for the connection.

Application:

- Select the appropriate scale in Nm or in-lbs. Unlock the micrometer knob.
- Adjust the micrometer knob so that "0" on the knob scale is aligned with the vertical line on the spanner arm.
- Turn the micrometer knob clockwise until the desired torque is set.
- The desired torque is set when the scale on the micrometer knob is aligned with the vertical line on the key arm.
- Then lock the micrometer knob and set the corresponding direction of rotation of the ratchet, after which the spanner is ready for use.
- Put the corresponding bushing on the driver of the spanner. When tightening, the set torque is reached when the spanner clicks into place. 
When you hear or feel a click, stop tightening.
