No, but it will go up 25% in price!
I never heard of the "don't use the upper 20%" of any test equipment, since that is where the tolerance specification is measured.
My cheapie click torque wrenches were close on the Snap-On truck tester, but my Snap-on had to go in for an $80 calibration. I got it used, so I do not know how it was treated by prior owner.Frank DuVal

I seem to remember the tool dealers that came around to service shops had a device to check/calibrate torque wrenches.

Occasionally compare my "click" torque wrench w/ another (of same capacity) at low, medium, high range of scale. Use a simple combination of socket adapters (may make a dedicated adapter one of these days). as long as the two units compare within a few pounds (Approx. five pounds at 100 pound test) I'm happy.
Anyone else use this test??

PaultkNo, because that just shows correlation, not correctness.

Got a 50-250 ft-lb digital wrench last week. Why not, I can afford it...
I decided to check out the old wrench and had around a pair of nuts welded together with a "crowfoot" stubby open-end wrench in between I made for some custom repair... So, clamped the old wrench in the bench vice, then sockets, this double nut, and the new wrench.
I set the old one for 130 ft-lbs and applied torque with the new wrench that was set to alarm at 130 ft-lbs.
Alarm went off before old wrench clicked. I tried it again at 100ft-lbs and got similar results. At 50 ft-lbs it was about right. So, it seems the wrench may have "over-torqued" those bolts??
Current plans are to tear into the tractor some this week on vacation. I am not too hopeful re-torque will fix issues and I see R&R the head again. Hopefully the rain not too bad. Working in a dark & damp shed is not a fun deal.
What sucks about this is you have to take the steering shaft off that runs over the valve cover to get that off. Then the rocker shaft has to be off to get at some of the head bolts. So, afterwards you must recheck the valve rocker clearances. Not a real quick project and why I wonder how one is supposed to do this "hot".

I've used the digital torque adapter and recalibrated several click torque wrenches, because they're so convenient for running head and main bolts; that's the big IF one can trust the click.
