You prove my point about this being a piece of junk IMO. My Stahlwill 5-36 ft lb is accurate throughout the scale.
Well, a HF torque wrench is not as nice as a Stahlwill torque wrench that is many times more expensive. That's not really a surprise.
Stahlwille may be an exception.
This manual claimssome of their torque wrenches are usable from 5% - 100% of full scale. You pay a pretty penny for the broader range of the Stahlwille, probably more than most members on this forum who aren't pros can afford.
That's good to see that the Stahllwille has a broader torque range, but it's not the norm for the American torque wrenches. I agree the labeling of many torque wrenches is misleading. Tool buyers need to be aware of the usable torque range when buying a torque wrench.
Check out
this $500 Snap-on Techangle torque wrench.
In the description it says this, claiming a 12.5 - 250 ft-lbs rating:
Quote:
Torque Wrench, Electronic, TECHANGLE™, Flex Ratchet,
12.5 to 250 ft. lbs., 1/2" drive
But then further down they admit that it's really accurate from 20 - 100% full scale. (50 - 250 ft-lbs.):

Note:
The certification of accuracy provided per ASME and ISO Standards is 20% to 100% of full scale.
In another
Snap-on document it says this:
Quote:
Torque wrenches that are scaled below 20% of
full scale may not be accurate and may lead
users to operate them below their useful
range. Select a torque wrench so your working
range falls near the mid point of its capacity.
I'm not arguing that the HF torque wrenches are better than more expensive torque wrenches, because they're not. But they're generally accurate and work well for a lot of people when used for the correct job.
Yah, it helps to know the limits of a tool before buying it. For my use I knew the HF wrench was ideal for the work I needed, and as I said, I inspected the tool before buying it, not afterward. So I didn't have any suprises when it came time to use it.
