Problem with the HF torque wrenches is you throw them away when they break.Calibration places won't even touch them.

Not that I'd go to the expense of having a cheap torque wrench calibrated, but how do you know this?
Do you have first-hand knowledge of this? Why wouldn't a calibration shop take one in?

The full article showed the Craftsman, HF, and Snap-On all within a margin of error of one another. The digital torque adapter from HF was by far the most accurate and repeatable in their testing. I own a craftsman, but I only use it for lug nuts and suspension. I'd get it certified before building an engine or anything like that.
No doubt in part because no one in their right mind would pay twice the purchase price to have an old one worked on.
"Oh, you mean you guys won't recalibrate this for me? Well drat, guess I'll just run to the store and buy 2 more of them for what I was going to hand you assuming there were no other problems."![]()
So, they'd refuse to calibrate it because most people wouldn't bring it in?
Like I said, I doubt most people would, but I don't see that as being a reason they'd refuse the business. When/if my Craftsman torque wrenches get to the point of requiring recalibration, I'll look to buy something better that would be worth the expense.
Is there a technical reason for it? Is there something that makes an HF torque wrench unable to be calibrated?
I won't profess my expertise in this arena, but 20 lb-ft seems a bit low for a 1/2" drive - that seems more in the arena of a 3/8" drive.
Most 1/2" seem to start arount 50 lb-ft.
If the Proto meets your requirements, I don't think it's a bad option at all.
I see in 1/2" drive, Proto makes a 16-80 lb-ft, a 30-150 lb-ft and a 50-250 lb-ft.
I've never seen a clicker in 1/2 that didn't go to 10?
my wish list is a rachet clicker 1/2 drive 20-150 ft lbs budget $200 no way in hell can i afford snap on
Lots of them don't go to 10 ft-lbs. That's very low for a large wrench.
Try bringing a Polaroid or a Mickey Mouse camera to a real camera shop and ask them to work on it.
Places that specialize in one thing tend to get kind of passionate about that thing. My small engine guy won't touch low-rent Chinese equipment, either. I can imagine that since the cost is often well under what they'd want to fix it for, they've had plenty of people trying to cheap out on fixing it, too.
Note: We do not service foreign manufactured torque wrenches.
As noted, I have read before that the calibration places won't service imported wrenches.
I don't think that matters in the case of the HF wrench. It's so cheap that if it ever broke just toss it in the scrap bin.
My 1/2" HF torque wrench is about 8 years old and has been used a lot. It still works well and it is still in spec, according to my torque adapter. If it broke tomorrow, I would go to HF and buy another one. My CDI and Armstrong torque wrenches are nicer, but the HF unit works fine.
