What I don't understand is, why did they stop it at 283 ft lbs? I think it's because it breaks soon after that, they just want you to think it could go well over 300.

283 ft-lbs = 3400 in-lbs

It seems that the tester stopped there because that is what they test them to i.e. what torque they are designed to carry. I don't think it was a test to failure.

...In any case, if you are putting that much force on an 11" ratchet you are using the wrong tool for the job.

I'm sure they have plenty of times, but for QC they just go to a certain torque. Breaking stuff is cool, though :thumbup:

What do you estimate the fl lbs of a 700lb toolbox pulling down halfway on a F80 are? I used to know how to calculate that, then I got lazy with fancy torque wrenches

No need to estimate...

Torque = Force X Distance
F80 length = 7 11/32" / 2 = 3.672"
Force = 700 lb

Torque = 700 lb X 3.672" = 2570 in-lb / 12in/ft = 214 ft-lb :beer:
