Birzman M-Torque 4

A multi-tool featuring an integrated 5Nm torque wrench.

As you tighten a bolt with M-Torque in hand, the force through your thumb pushes on the raised button.

When this force reaches 5Nm, the button will give a reassuring click, indicating the bolt has been tightened to the correct torque value, just as it would be in a workshop.
