torque wrench ft lbs
Loosen a click-type torque wrench all the way = off calibration?
Well I went to Harbor Freight today and purchased my first torque wrench. It's an 18" 20-150lb 1/2" drive click-type, and it was <$30!
I got it home and took it out of the packaging. While reading the instructions I absent-mindedly loosened the grip all the way and felt all the tension come off the inner spring. I quickly tightened it back to 0lbs/ft fearing that I threw off the calibration (the instructions said in bold print "DO NOT LOOSEN ALL THE WAY."
Went to my car and torqued my lugnuts to 70 lbs/ft and they feel like they're on there good and tight.
Does loosening a click-type torque wrench all the way cause it to lose calibration?
Don't worry too much about it. It's a safety thing so the spring won't dismount itself if you drop it or something.
