The torque spec on my crimper manual was off by 15%, checked it against the factory gauge
Was down in Waco last month redoing a run of 500MCM and my crimps were coming out loose, pulled the manual and it said 12 ft-lbs but the calibration sheet on my tester said 10.2, that little difference was the whole problem. Anyone else ever catch their tools lying to them like this or am I just unlucky with the batch I got?
That 15% gap is nothing compared to what happens after a few hundred cycles on the tool, since springs and linkages wear and the wrench or gauge drifts way more than the book shows. A cal sheet dated the day it left the factory tells you nothing about the day you're actually pulling on it. Get the tester checked on a schedule and trust the number in front of you, not the paper in the box.
