awesome you posted this thread, i'm going threw the same exact thing right now...i got an inch lbs but no foot lbs....asked my bud to bring his foot lbs to work tommorow so i can pic it up. i'll just keep barrowin other ppls until i need to buy my own
Just get a cheap "bend" bar torque wrench and do the math. One foot pound equals twelve inch pounds, two foot pounds equals 24 inch pounds......and so on. Click wrenches, like the craftsman, are inherently inaccurate because they have no defined mathematical length. They are close, but you can't do the big and small jobs with one wrench.
You're right in your calculations. But in the quote about the click wrenches (AKA Micrometer Torque Wrenches) you couldn't be farther from the truth. These are actually closer than the bend bar(AKA BEAM or Deflecting Beam). This is why they are used in Aviation. And even thought the inch pound to foot pound conversion works well...you should always use a specific wrench for each! I started out My military career in the Air Force and micrometer torque wrenches are the standard.
Dial Type Torque Wrenches are the only ones that beat the micrometer for close tolerances.
While the Deflecting beam and beam bars are inherently accurate due to their simple nature...remember this...close spaces at times preclude you from using them...also they are often misread by the user. this is why micrometer torque wrenches are the most popular.
On last note...any and all torque wrenches can lose their basic calibration. It's a good thing to have them check out on a yearly basis!
Ride Safe, Mike

Got one at Home Depot about 5 years ago. Got it out today to use and it was broke(lent it to a friend) Called Home depot and the said it has a lifetime waranty. I had no reciept and they said no problem.So now I have a brand new one. Craftsman has no waranty on there torque wrenchs. My spelling sucks. LOL
I have two ft-lb and two inch-lb wrenches. I had an inch-lb wrench from Harbor Freight and while I was using it once, I didn't think it was reading correctly so I bought a Craftsman. The Craftsman confirmed the readings on the Harbor Freight wrench. I'd get both and unless you are planning to do some serious wrenching, I'd look for a deal at Harbor Freight.
As long as the torque wrenches are new...calibration and accuracy aren't usually an issue. It's after a year or two of rolling around in the toolbox drawer, being dropped and abused when the need for calibration is paramount. And you'll find alot of the Harbor Freight and other discount tool warehouses just sell off-label stuff made by the larger more Main Stream Name companies for less. Isn't Free enterprise awesome!
