Torque screwdriver
« on: June 30, 2018, 09:06 AM »
I'm looking for a good torque screwdriver -- something where I can measure/set the exact Nm.  Any recommendations?

Wera.  There are a range of preset and variable options available, pick the one that suits your needs.  They also have a pistol grip version if you need more leverage, but you’ll find yourself seating the screw with another driver that spins faster, then switching to this one to do the final torque.  It’s also pricey, so I just went with a straight handle

Edit...
Just looked again and their preset models are adjustable internally with a wrench.  Not something you would want to do everyday, but at least you have the option.  I have the variable, but you do need to wind it back down to zero like the clicker style torque wrenches to keep it accurate.  You probably don’t have to do that with the preset models (not sure).

I like Snap-On products. The nice thing is the local Snap-On guy will order in what I want and I can play with it to see if it will work for me. Nothing better than some hands on time.

Thanks for the replies.  Think I'm going to go with the Wera -- my specific application calls for 45lbs torque, so I have to go with the pistol grip.

I have this one, but can't really tell you how it compares with other options.   [unsure]  Works fine - no complaints.

Or in-oz? I needed one in in-oz for properly torquing PVDF fasteners in PVC panels.

If it is 45 inch/pounds, you might want to consider something like the Wheeler Firearms Accurizing Torque Wrench.  I have one, and it is very good quality.  A kit with 10 bits in a plastic case is $40-45 on Amazon.  It accepts 1/4" bits, so you can use those that you already have. Accuracy is +/- 2 inch/pounds, with a range of from 10 to 65 inch/pounds. 
Gunsmiths require accuracy and repeatability when assembling mechanisms for firearms.

That’s why I bought the Felo torque-limiting screwdrivers. Although more money, the overall quality and feel are better.

Felo has an adapter to use with 1/4” hex bits. Most of the bits that I use are Brownells or Snap-on.

That's the nice thing about Felo and Snap-on, they both offer lifetime warranties.  [smile]

Took delivery of the Wera yesterday and am now putting it to use rotating the carbide inserts on my Byrd Shelix cutterhead for my Dewalt 735 (almost 1 year of service life on 1 of the 4 edges of the insert -- not bad!).  The pistol grip is fine in any case, as I'm doing most of the screwing/unscrewing with the CXS, and only using the Wera for the initial unseating and the final torquing.

Thanks again for the recommendations.

Funny this is exactly what I have been thinking a torque screwdriver would be good for.  Need to keep it mind if I ever upgrade to the Shelix.

@ear3 just make sure you relieve tension on the torque driver after use. It keeps it operating correctly.

That goes for any torque wrench or driver.
I take mine back to 15% of full range.
No or zero tension is also not good.
