Hot or Not? Harbor Freight Torque Wrenches
By Chuck Cage
We’ve seen quite a bit of unfocused discussion regarding the quality of Harbor Freight’s extremely cheap torque wrenches, so we thought we’d ask the question straight up: are they accurate enough for real use, or are they a crap shoot?
One reader mentioned a while back that he put an HF 1/4″ torque wrench on his tester at work and it was quite accurate. Though I have no evidence to support it with HF’s wrenches specifically, it’s been my experience that many times cheap-ass tools aren’t necessarily all bad — quality simply varies more tool to tool because of poor quality control.
On a side note, poor QC is a very effective way to save production cost. If you’ve ever visited a quality tool plant — as we have — you’d be blown away by the sheer manpower that goes into good QC.
And at $12 for a 1/2″ torque wrench, you’ve got to figure they’re saving dough somewhere.
Anyway, what say you? If you have data (or experience) with these HF wrenches, jump in and let us know in comments.

I’ve bought two from Harbor Frieght. The small one was crap, but the bigger one was decent.

I would never buy a cheap torque wrench, you really do get what you pay for. I bought a very cheap one from a discount tool store, I was using it to tighten up a bolt on the oil pump of my truck to correct “factory” setting. Bang! cracked the casing to the oil pump. I later got a hold of my Grandpa’s Snap-on torque wrenches and was finally able to put in a new oil pump and torq’ it up to the correct setting without fear of it cracking.

I vote “Not”. On a project I was working on last year at work we bought a couple of the HF torque wrenches since we felt that where were working (in a marine environment) we would be very likely to loose them and would rather have lost a sub $20 tool rather than a $100+ tool. During the course of work we found, and later verified using some pretty good instrumentation in laboratory conditions, that the repeatability of individual tools and variance between tools was _VERY_ large (which would support your poor QC argument).

Not: I use my HF Torque Wrench as an inbetween for my regular ratchet and the breaker bar, it’s a good size for that. Notsomuch for torquing stuff.

A torque wrench for regular wrench duty? Do you use chrome sockets with your impact wrench too?

I was the guy that put his 1/4″ HF wrench on a troque analyser. Mine was spot on across the full adjustment range. However I’m more then will to admit that my sample size was too small.
I think this sounds like just the job for Toolmonger. How about you buy 5-10 of each size torque wrennch and then find a torque meter to chek them. Throw in a little statistical analysis and a sample set of wrenches from higher end manufactures and you’ve got a story!
Not that they are that expensive but I bet you can return them after you’re done.

I was given one as a gift about a year ago, and a few months ago I had a use for a large torque wrench so I took it for its maiden voyage. Darned thing wouldn’t break (click) at all, it amounted to little more than a large, cheap, 1/2″ ratchet.
Took it back to HF, and the cashier was happy to let me exchange it for another. This one works as well as it’s intended to, but for anything but the lowest settings, it’s easy to overtorque because if you’re pulling hard enough you’ll right past the vague ‘click’.
For $12, if it works it works, but I wouldn’t rely on it for anything too critical. Did a decent job torquing the studs when I replaced my sway bar bushings, but I wouldn’t trust it if I was torquing down an aluminum head.

Hot or Not? …. Is this a joke?
A 1/2″ drive torque wrench at 1/2 the price of a Craftsman 1/2″ drive rachet.
As Mr.T say’s “I piddy da’ fool”
As a wise man once told me, “A Fool and his money soon part”

Let’s face it, you don’t use a torque wrench because you want to be “somewhere in the ballpark,” you use one because torquing to the proper rate is mission critical to the job at hand.
If your using a torque wrench that you don’t trust, then in my opinion you might as well use that nifty ratchet that came with your socket set and save the $12. You’ll likely get the same results.
(Do me a favor, and don’t tighten any “torque to” type bolts with a HF torque wrench, huh)

I agree 100% with what Craig said above.
I never would have BOUGHT a HF torque wrench (if you’re reaching for a torque wrench, it’s a good bet you care enough about whatever you’re tightening, that it’s worth being accurate), but since I had it, I figured I may as well try it.
Not sure I have a good excuse for putting in the effort required to exchange the dead one for a less dead one, but “heck, I was there already” seems enough :).

It’s hot for the right job. I use mine primarily for wheel lug nuts, which AFAIK should be close to a certain torque, but don’t have to be dead on. I wouldn’t use it to rebuild an engine or anything that required alot of precision.
The main thing I like about these is that if you drop one there is no point in getting an expensive recalibration, just pitch it and buy another.

I almost bought a HF torque wrench, but decided to go pawn shopping for a used snap on. Either way, I’d have to get it calibrated before feeling comfortable using it.

Mine broke the first time I used it on higher torque setting. Worked ok on lower settings, but not sure how accurate it was. Won’t buy a cheap one again.

[...] Harbor Freight Torque Wrenches: Not. Everyone agreed that if you’re using a torque wrench, you need accuracy — and accuracy doesn’t come in packages this cheap. [...]

Old Donn - Yes, I use it as a in-between breaker, as it was completely useless as an actual torque wrench.
April 13th, 2007 at 11:25 am
Wow… Harbor Freight and Precision Instrument. Two things that DON”T go together….
August 9th, 2007 at 8:35 am
I have one, its great. Lots of people complain about ahrbor freight, but I have bought a LOT there and never had any problems. Definitely reccomend. These are truely ideal for the weekend warrior… for daily use, I dont know. But I dont need it for daily use.
The electric flyswatter is WONDERFUL, and when on sale for $1.99 its impossible to pass up!

I have just gone through two new 1/2″ Harbor Freight torque wrenches that will not “break” at any torque setting (i.e. they act like s simple ratchet). There will NOT be a third!

U jusat bought a 1/4 ” HF ( in lbs ) torque wrench . It did not click at a very low torque . I knew something was wrong so I didn’t go any further using it on the job. Since I have to gack to the store, I’ll try a couple more but basically thumbs down on these . I think that the cheapest Craftsman bram type would be better for those on budget .

I purchased a 1/4″ HF in lbs model torque wrench . It would not lick at any setting ether . Fortunately I noticed it early an didn’t damage the application I was working on . This taught me 2 lessons - (1) Always test a torqure wrench before your us it (2) don’t count on HF to sell working tool off the self .
Take a look at the DIY torque wrench tester ( thanks OP )

So the only guy with data says it is good and everyone else says they’re bad? Hmmm.
March 27th, 2008 at 7:37 pm
@Paul Baker: Well, the only guy with data says that his sample size of one worked as intended. Most of the “these things suck” posts were because the wrench was mechanically faulty — didn’t click, worked one time and then didn’t work again, etc. That speaks to a pretty bad quality control process and suggests that Jeremy’s good data may have been an anomaly rather than the norm. Like he said, though, his data isn’t worth much without a broader test.
@rkpatt: Love the homebrew test setup. If only I had a receiver hitch :-p

I don’t think I’d trust one for torquing down head bolts, but for the price I think they’re great for more forgiving applications like lug bolts. If you’ve got something you’re a bit wary of trusting to just the “feel”, but don’t want to shell out $100 on a wrench that will get used once or twice a year, the HF torque wrench is a no-brainer.
