Wheeler FAT Wrench

[MoreIsLess]

I am thinking about buying a Wheeler FAT wrench for various general gun maintenance tasks that arise. It only comes with 3 Allen bits, a 3/32, 7/64, 5/32. Where can I find additional bits that will work in this tool. This first thing I need to use it for is to torque down the red dot sight I put on my M&P CORE and I don't think any of the bits provided will fit the screws that Smith & Wesson provided for this.

The brownell screwdriver bits fit mine and I think it is a standard size where most bits will fit it .

Smith and Wesson is telling me that I need a 5/64" for the screws they provide and that one doesn't come with the Wheeler FAT

Solved. The set is $16.99, includes 5/64th bit. It took me about 1 minute to find it, most of that using Brownells' search bar.

I noticed that the Wheeler FAT wrench has torque adjustments from 10 to 65 in/lbs with 5 in/lb graduation. From videos I have watched, the required torque for the M&P screws is 12 in/lbs. Using this tool, would it be better to use 10 in/lbs or 15 in/lbs for that since there is no 12 setting. Is there really much difference between 10 and 15 in/lbs.

^^^^^ This is the reason I went with Brownells Torque limiting wrench, 1 in/lbs adjustments.

[Blue68f100]

Yes that's the one.

 

[MoreIsLess]

Yes that's the one.

Only thing is that one has a range of 15 in/lbs to 70 in/lbs and the Smith and Wesson screws require 12 in/lbs. Not sure if the difference between 12 and 15 in/lbs is enough to strip the threads or not

You can put the wrench between any settings no problem.

The adjustment on the Wheeler FAT Wrench is analog, so you can easily guessitmate 12in/lb.

Any 1/4”’Drive bits will fit the fat wrench.

I will need to confirm this but I think you can set it under 15 in/lbs. The calibration is done from 15-70, supplied with the unit. So you want know how accurate it is at that low of a setting.

If I recall someone makes a preset not adjustable screwdriver/torque wrench in the lower values. Can't recall where I saw them at though.

My Husky from Home Depot has 2 lb increments, 8-40: https://www.homedepot.com/p/Husky-1-4-in-Hex-Inch-Torque-Screw-Driver-H4DTRQ/204772217

I checked the Brownell's torque wrench and you can adj it lower but there is no marks except on the outer dial to go by. May work since you only need to go 3 in/lbs lower. Have no idea as to accuracy since it's below the calibrated range.

I have the digital FAT wrench, and it reads from 0-more than I can get on the handle, but I'm not sure as to accuracy.

I have the digital FAT wrench ...

There a digital Weaver FAT Wrench?

 

[Blue68f100]

Yes there is

5 inch/pound increments is why I didn't purchase the tool. You might consider biting the bullet, so to say, and get a mid range tool for about $150 with a wider range of torque and in 1 inch/pound increments. Sturdevant Richmont has such tools.

 

[Varminterror]

The FAT wrench can be set to any torque - it’s a continuum adjustment, not an increment. The SCALE, as in the label for the settings, is only marked in 5lb increments, but the tension can be adjusted anywhere between the marks. You can easily estimate 12in.lb. Between the hash marks.

It’s not the most accurate nor consistent tool, and there are a few tricks which can help a guy make it more repeatable, but for the money, the accuracy needed, and the precision needed for firearms owners, it’s more than sufficient.
