The Zéfal Z Torque Wrench is a precision mechanical torque wrench designed by the French brand Zéfal, primarily for bike shops and home maintenance of modern bicycles. It is ideal for the safe assembly of sensitive components, especially those made of carbon and lightweight aluminium, which are at risk of breaking if overtightened.

Key features and ergonomics

Retaining ring: On the bottom of the handle you will find a locking ring that prevents accidental turning and changing the value during tightening.

Audible click. At this point, it is necessary to stop pushing immediately.

?? Important maintenance rule: Like any mechanical torque wrench, it must always be loosened to the minimum value (2 Nm) when the job is finished, so that the internal spring does not tire and the wrench retains its precision. Also, never use it as a regular ratchet to loosen stuck screws.
