Boeing gets all their torque from Harbor Freight.
I have the half inch version of that. Seems fine.
True Story:
A company I used to work for back in the 80’s and 90’s, was a major subcontractor to Martin-Marietta for the VLS Missile Launch System for the Navy’s new destroyers.
I was the PMEL Calibration supervisor.
One of the subassemblies was a large metal door that had about 50 or so fuseholders on it. These were very expensive, about $100 each, waterproof sealed fuseholders that held large fuses about the size of your index finger.
One day they started having a large number of cracked fuseholders for some odd reason, about half of them on each panel.
The first suspect was the torque wrench that was used to install the retaining nuts.
The Quality Engineer and Mechanical Engineer brought the tool to the Calibration Lab and I put it on the Torque Tester Machine. It was perfect. The QAE was rather perplexed and dubious of the machine, but took the wrench back to the Production Line and they decided witness the installation of the fuse holders on a new panel.
The assembler, a young girl, took the wrench and proceeded to install the fuse holders.
She used the torque wrench to tighten the retaining nut and the wrench went ‘click’ as it was supposed to when the proper torque had been applied.
BUT to their surprise, she did not stop! She kept on tightening the nut!
When asked why she did that she replied, “I do that to all the fuse holders! It doesn’t ‘feel’ tight enough to me, so I go around a couple more times just to make sure!”
After that the toque wrench was replaced with a ‘breakover’ type that cannot be used past its preset torque limit.
Mystery solved...........................
