Good torque wrench? Suggestions welcome

Is there any torque wrench I should look at before just getting one from my local hardware store? They've got a 5 to 80 pound that looks like it will do the job.

I bought a CDI from Uncle Sam's Retail Outlet. Overkill? Maybe, but it's my understanding CDI makes the torque wrenches for Snap-On. The one I received had some dirt and stuff on the case, but the wrench still had the factory paper thing over the head.

For firearms applications, you are dealing with torques in inch-pounds, not foot pounds. A torque meter is a little bit overkill, just buy one of the FAT Wrencehs from Midway, quick, easy, neat.

Good point Scorch, I was assuming he was wanting to put on AR barrel nuts.

Just as a side note, both Proto and Snapon, along with Mack, make superior tools.
My torque wrenches of those brands, acquired nearly 50 years ago, are still going strong and accurate whatever size and use is needed.

Venom1956,

As you might guess from the responses, what you want to do with the wrench matters. Barrels? Then you want something with a maximum capable of 50 ft-lbs. If you want this for scope rings and action screws, something with 50 or 60 inch-lbs maximum range is appropriate.

The FAT wrench comes with a calibration paper to show actual error at time of calibration. If you are making a career of this work, Start looking at Grainger or some other vendor of higher end tools as suggested above. For most applications in Gunsmithing the absolute accuracy isn't a stiff requirement and something that is good to within ±10% accuracy will generally do just fine.

Yeah ar barrels. For what i am asking. Im not sure if there is a benefit using a specific ar torque wrench or just any one will do.

I hadnt considered for scope mounting thats a good idea

Intended use is important.

A 6-40 screw needs 12 in. lbs. steel on steel but 6.6 going into 2024 Aluminum.


Also, you never use the bottom 20% of range as accuracy suffers too much. That's why some tools range from 20 - 100 and not 0 - 100. Your higher quality tools will exclude the bottom 20% from their range.

To help keep your adjustable tool in tolerance, set it to the lowest setting before putting it away.
