Torque Wrench Comparison Test

I’ve got the Precision Instruments 1/2” split beam. Great tool. Surprised by the accuracy result, but the precision is no surprise. What’s interesting is that they tested a well used one, and it was still very precise, even if it was due for calibration. Even well used, it was still performing well.

A professional tool.

They didn’t test CDI tools torque wrenches. That’s a big oversight.

I’ve got a couple (1/4” and 3/8”). They’re reasonably priced, finely made, and supported by Snap On.

For example:

So far I've had good luck buying used tools, as long as the seller will accept returns if they can not be calibrated.

I also bought a set of torque wrenches from Capri, which I think are the same as Tekton. They were very accurate and required no adjustment out of the box. For the price, that's what I chose for my home/travel box. The good tools are in my work box.

I do too...

I forget where I saw it, but I recall seeing that Precision instruments claims that their split beam wrenches are less accurate than others. Not much, I think it was like 4% vs 3%, not a huge deal.

I don’t think that accuracy is that concerning, especially at the relatively high values used here. For something that needs repeated torquing, being precise (thinking for example, lug bolts that could cause rotor warping) is more important. Consistent, repeated outcome versus being off by a few ft-lb.

For those who don’t recall the difference, from wiki:

Someone here a few years ago sent a precision split beam 250ft/lb wrench out for calibration, after several years of daily use torquing out nuts , it was still in spec.
When I get home tonight I'll search for the thread
 
I like the Home Depot Husky ones. Three percent accuracy rating, come with a test cert like many do, and a no limit lifetime warranty is the deal maker. They have a couple sales per year on them. They appear to be modern versions of the Armstrong and are made by Apex now. The Capri's for $25 on sale were a nice deal too, and having two of one type means they can check one another. If both torque the same, it is highly likely the torque hasn't slipped.
 
Split beams really hold up well even in abusive conditions. I love split beams, the only real issues with them is their physical size (larger than normal clickers or electronics) and they cannot torque left handed threads (sucks if you own an old Mopar).
They are not well suited and AFAIK not available for fasteners that have very low torque specs.
 
Glad to see a test. I have a nice Husky that my mom bought for me and a smaller HF one. It may not be nice compared to these but I like it. I’ve never used a beam style wrench to be honest. Wonder if it’s worth investing in?

I use this PI split-beam for 13-18 ft-lbs spark plugs:

Any reason I should reconsider?
 
might one with slightly higher range be more broadly helpful? Thinking a model that does 750 or 1000 in lb.
I have:

1/4" M1R200HX - 30 to 200 inch lbs (2.5 ft lbs - 16.67 ft lbs)

3/8" C2FR600H - 100 to 600 inch lbs (8.3 ft lbs - 50 ft lbs)

1/2" C3FR250F - 50 to 250 ft lbs.

Ideally I would also like to have a 3/8" that goes from 50-100 ft-lbs with angle capabilities.
