It is simply true.
It is zero in it's resting position. :)

Yes. It's also hard to set it up to specs that are between two numbers (IE, my stem bolts requires 5.5nm & the dials are 0,2,4,6,8,etc.). You need to stop the red marker at 3/4 between the 4 and the 6 which is a little complicated.

Exactly. lol

Yeah, the point that you missed is that you don't need to do anything with the Ti Torque to keep them accurate, as you claimed must be done with all torque wrenches.

It also has markings for common in between torque values like 4.5nm and 5.5nm so things aren't "complicated," to use your wording.

Incorrect. Some torque wrenches require setting them to a low setting and not zero. When I worked at Boeing all torque wrenches required a non use setting in the low range but not zero. I suppose those engineer types that determined that have no clue.

Most of them in fact. Low or zero...as long as you unwind it after use. I always put mines at the lowest possible setting after every use to remove tension in the spring. It's just better in the long run & to keep accuracy.

Accuracy is important, especially in the aerospace industry.

A torque wrench in regular use doesn’t need to be wound back. If you expect to store a torque wrench for more than a few weeks, always wind it down to the lowest scale setting (never to zero).

Storing a fully loaded torque wrench can result in a set in the spring, weakening the spring over time. But if you completely offload the spring to the zero setting, other components within the wrench may move a little. And in the world of torque, a little is a lot. Reapplying spring compression will shift orientation of these components, affecting accuracy.

This is from one of several web sites that specifically say never zero the wrench. FYI, if I turned in a torque wrench set to zero at Boeing, it probably would start a line check on every airplane it was used on going back to last recal. Personally, I owned a Snap On torque wrench that did not require any adjustment prior to storage, it required recalibration a lot. More so than any wrench I’ve ever used.

Indeed. I can only imagine the consequences...
