Giving this thread a little 'bump';
I bought a torque SO torque wrench many years ago from a retired mechanic - I found in another thread here mine is discontinued and no service parts are out there (good thing mine seem A-ok for now!)
Mine is a QJR-3220 - I am posting in this thread rather than the QJR-3205 thread I just found because that thread is ten years old, and this thread should suffice:
The Snap On torque wrenches we have at work have the date on the bottom of the handle, but they are from the 90s-2000s. In this format: 07-98, 11-01, etc.
I can see just above the lock ring an AA18756
Just above the lock ring on the dial collar (opposite of the Snap-On logo and model number) is 4-79
Does this mean this wrench was manufactured April 1979 - or is the other code the one I need to decipher?
Is there another discussion (that I maybe haven't found yet) which spells out where Snap-On puts date codes on various tools(?) - because I have a 1/2" drive SL715 that I'd like to be able to date...
