Today I was comparing my torque wrenches and noticed that the Harbor Freight 3/8" (clicker) has a plug covering a hex screw, about midway on the shaft. I believe it is calibrated like the 1/2" model that doesn't have that screw (using calibration sleeve below the scale.) Any ideas - I have no ideas.

Ah ha. That makes sense, but I was confused by the fact that it has the same sleeve adjustment as the 1/2" unit, but the 1/2" wrench doesn't have the set screw.
Thanks for the explanation.
