WERA C-SERIES REVIEW - BY PETER BRETT


Wera and the era of the ‘torqueys’


A FLICK through the latest Wera product catalogue will confi rm the company is no stranger to the ‘torqueys’ – tools that control the level of torque for tightening various bolts and screws.


As machines and components have become more advanced, the need to control the levels of torque of various fi xings has become very important.


'As tight as you can get it' is not an acceptable procedure when working on a carbon fi bre structure, or on an electronic device that needs a correct torque to maintain electrical contacts.


The Wera torque tool range provides ultra-precise micro screwdrivers to standard and VDE formats, right the way to a monster torque wrench capable of delivering torque tightening from 200Nm to 1000Nm.


Clearly the latter have more sophisticated ‘innards’ to ensure accurate and consistent torque delivery for a wider range of tasks.


Eisenwarenmesse 2018 (Cologne Tool Fair) was the setting for the launch of Wera’s Click-Torque range of wrenches – and an array it was too.


To ensure all bases were covered the range stretches from the A5 & A6 ¼” drive 2.5 – 25Nm right through to the E, which is a ¾” drive.


C1 – C5 Range


The C1 reversible ratchet wrench comes with a 10 to 50Nm capability up to the C5 with an 80-400Nm available. Add in the Click Torque E and the Click Torque X series for use with insert tools and it is clear Wera takes torque tools extremely seriously.


Click Torque C3


I was sent a Click Torque C3 to review, which is in the middle of the C range (1/2”) of wrenches and is a typical example of the ergonomics and operation of the Wera torque wrenches – so readers can generalise a bit about how the rest work.


The Click Torque C3 announces its capability with green lettering by the ratchet head reading 40-200Nm, meaning it would be a good choice for mechanics, AA Patrol Staff and such like.


This precision tool is just over 51cm long and arrived packaged in a snug square plastic box, which is great for storage and would suit any retail display.


Also in the case was the all-important calibration certifi cate and Certifi cate of


Conformity, which should be kept safe.


Torque wrenches need regular calibration after a fi xed number of work cycles to ensure continuing accuracy. I was pleased to note my sample, according to the certifi cate, was well within the 3% tolerance allowed by the standards testing authorities.


Some features


As we would expect from a Wera tool, the ratchet head is made from fi nely fi nished alloy with a ½ inch square drive. This drive has a ball-bearing socket retainer and a socket release button.
