I just ordered on Amazone TW-1 torque wrench manufactured by Warne. After placing the order I found out that TW-1 has not adjustable settings of 25 in/lb. I called Warne and the technician confirmed that it is an industry standard. I wonder if 25 in/lb can be applied to any 30mm or similar rings/scope or different scopes of the same diameter may have different requirements.

Many cap screws list at 15-20 in lbs. and the ones mounting to the base can be higher than 25 in lb. -
Most of the information I have come across specifically states ~15 in/lbs. Vortex recommended the range of 15-18 in/lbs while my American Defense mount states 20-25 in/lbs. The latter are split ring and may account for the difference. Your best best is to call the manufacturer of the mount and get their suggested torque amount.Comment

It will vary based on manufacture... Ill always follow manufacture recommendations, and if they don't publish values I will use generic values based on the size of the fastener and the material I am working with.
Here is an example.
Lots of torque options out there, I don't really trust "clickers" for the small stuff unless you are buying $$$.
I do like the beam style... I've mounted many bases, rings, and ring half's using it. Never a problem, and easy to control.

Sorry...I wasn't specific. I meant call the manufacturer of the mount / scope rings. Unless you are also using Hi Lux rings as well.
Honestly though, I am not entirely sure how to proceed if a scope's upper strength limit falls under the rings required torque minimum to hold true. I never encountered the issue.Comment

Scope damage, or the possibility of it is greatly increased when you are using rings of poor/lesser quality. If the rings are applying presser an in an uneven manner, it’s possible for LESS torque to damage the scope vs more torque from rings which were made better.
The flip side, if the rings are not holding well, either from poor manufacturing or the scope tube not being aligned between the two ring halves, you might end up applying more torque to hold it, ultimately damaging the scope.
You want good surface area contact and concentricity, and even minimal torque will provide ample clamping power.
Aadmount has some good imagery on their website to illustrate what I am saying...
Scroll down to "Preventing Scope Damage"
"Above shows how the carefully chosen geometry gives the ring the right stiffnesses in the right places to ensure it compresses the scope tube evenly around its circumference. This not only provides a better grip on the scope, but prevents "tube pinching," where the rings flex inward on the sides pinching the scope tube, which is a common problem with many other brands of scope rings and is a large cause of ring marks."

You really do not need a torque wrench to mount scopes.
I spent about $250 on my low inch-lb/N-m torque wrench, but truthfully, I no longer use a a torque wrench. I prefer using my hands to feel the proper torque rather than a generic spec. Relying on torque specs can get you in trouble if there are other issues going on. Mainly, it's easy to break/bend things by setting a torque wrench and rotating instead of feeling what's going on. Frequently the good torque wrenches have too much leverage to provide you with the sensation you want.Comment

I have a friend who is a mechanic and it’s kind of the same way… chock it up to a lot of wrench time and experience. Over time I’m sure things can “feel right”.
I got comfortable using my beam style wrench, with that tool I developed some feedback. I know what it’s supposed to feel like with that tool. I would venture to guess for most folks, including myself, it’s better to have one than not. I’m one of those notorious “over torquers”
I’ve never once had a problem with ring marks, damaged fasteners or hardware, install coming loose, or anything like that when I was using my torque wrench.ExtremeXComment

Great info...thanks for that.Comment

Thanks guys. It is very helpful.sigpicComment

As long as you are compulsive enough to get a torque wrench to just mount a scope, you ought to get a set of feeler gauges to make sure it is mounted perfectly straight.Comment

My two scope mounts are a good illustration of ExtremX's comments. Both hold same Hi-Lux CMR 30mm scopes. The MidWest Industry mount holds zero even with screws set relatively loose. On the second mount from Burris mounting screws should be set really tight to prevent the scope shifting from recoil. My concern is not to overscrew the second one. I guess I will use both a tool ($20 amazon investment is made anyway) and my hands feeling to back up tool's clicks. Park tool TW-1 is an interesting one from a biking tools company. If it works for bikes I guess it will work for rifles.
Thanks for the info.Last edited by APV; 07-25-2015, 12:01 PM.sigpicComment

+1 on the feeler gauges JMP mentioned... that what I use to shim the scopes level. I did the bubble level thing for a while but found it to be unreliable and a complete waste of time.
The Park tool is good, a friend recommended it to me since I needed a low value inch/lb wrench to add to my tool box. I use it for more than just scope mounting... its worked out well for me over the years for multiple applications.
If you really want something field portable, or just for the range bag, check out the Borka torque wrench. http://www.shooterstools.com/ExtremeXComment
