Hi Michel, while you're entitled to your *opinion* on the subject of
torque wrenches, your comments are riddled with inaccuracies...
In the past several months we've posted information that should be
useful in determining a quality torque wrench from a "club". You may
want to check the archives for these postings.
- While in Germany last November, I noted that they re-calibrate
"clicker style" torque devices at the German car factory production
areas every few HOURS because they go out of calibration! ***
For your information, a Beam Style Torque Wrench is usually MUCH more
accurate than traditional "clicker style" T/Wrenches... See the warranty
and calibration specs that come with the tool, then review Hooke's Law
for a better understanding of this subject.
While improper installation and poor quality tools do lead to mechanical
problems, the BMW head bolt issue was simply a bolt problem, not an
It's my opinion that anyone who owns a BMW probably has a better
appreciation for quality and engineering than the average person looking
for a "club". That's why as Engine Designers and German engine
specialists we provide only true Aircraft Quality T/Wrenches for
installation of our Aerospace fasteners. Info. available at our website
if you're interested.
