Torque Wreches Tested - Harbor Freight
I've owned and used the HF 1/4", 3/8" and 1/2" torque wrenches for about five years. Read good reviews but always had that "$16 torque wrench" feeling in the back of my head when using.
This week our metrology shop got two new torque analyzers. I brought all three wrenches in today and we ran them through the settings.
1/4" in/lb tested at 35, 55, 100 and was within the 2.5 in/lb increment on the scale
3/8" ft/lb tested at 20, 60, 80 and was also within the 2.5 ft/lb increment on the scale
1/2" ft/lb tested at 85, 100, 120, again within the increment of 2.5 ft/lb
In fact most all broke right on. We both ran the tests and repeated (sorry, no official gage R&R). The metrology guy was impressed and commented on his box of Craftsman and Snap On wrenches.
I'll note, we did a few "back off tests" in case we run into reverse threads. The readings were a bit higher here with 5 in/lb and 5 ft/lb being seen repeatedly...
i.e: Set at 80 ft/lb the scale stated 85 ft/lb
Got a doo to do in a couple more thousand miles and will feel a little better knowing these results.
