Torque Wrench Accuracy- How to easily test
Guys, recently I was torquing a bold down on the C5 suspension and I just had that feeling that I was going way too tight and I was wondering if my torque wrench is no longer accurate!
It bothered me - so I found out how to make sure my torque wrench is in fact accurate and now I can sleep at night knowing my repair is correct.
I put together this short video showing the process.

Good video!
Where I used to work, we had a "calibration lab", that could verify the accuracy of ANY measuring device you could imagine, be it torque wrenches, Vernier calipers, pressure gauges, "jo blocks", whatever. I retired, and miss that "perk".....

Today I learned what a foot-pound actually is.
I should check mine. It's probably scary.

Great vid Ken....Now how can I do that with my inch pound torque wrench?

Been using that method, 12" and 50 lb weight, for the last 20 years. Do it every January 2 on all my torque wrenches. It is scarry how much some will change in a year and how some have been very consistent.

We too have a “cal lab” at the airlines since many of the tools have to be super accurate sometimes down to the ten thousandths of an inch !!...took my 40 year old Craftsman torque wrench in for a check up last year and it was still accurate to 1 foot pound...trick to keeping it accurate is DON’T drop it !!

It's also important to "zero out" the wrench when you finish using it. I, too, had a 30+ year old Craftsman torque wrench that was also very accurate....right up to the day that it's internal spring reached it's "fatigue point" and broke.

Mine was off by quite a bit and purchased in the early 90's. Easily brought back into calibration though - now I am much more confident when torquing a critical fastener!
Report back the findings if you would!
