Gentlemen
      This has helped immeasurably. The rifle is in the vice with the base mounted. Warne had no torque values for the top of the rings. It looks like between 15-20 in lb will do the trick. Thank you very much.

In calculating the max torque for scope base screws, the threshold between the male and female threads failing is at 1 to 1.2 times the screw root in engagement.

With that I can predict the failure threshold for various lubricants.

I do not verify with destructive tests on actual rifle receivers, but with equivalent soft steel plates of the same thickness.

Use  Unbrako screws [180 ksi steel]

If you are inclined to calculation and verification, I would suggest three levels:
1) Clean and dry
2) oil or grease
3) wax.

Calibrate the toque wrench with a weight measured on a balance beam.

I think that this should be put into a format that Anyone can use. 

If we could identify the ring type or the base type and than identify the torque specs.

I personally would find great value in that and then I would hand it out to many people who ask.

Right now I just refer everyone to buy a Wheeler Torque Wrench and tell them not to exceed 20 on the rings and 50 on the bases.

I never knew I was so far off.

Hope no one ever broke anything...Big Grin

fwiw

Wouldnt it be nice it there was simply an industry standard. Head Banger  I can tell you that the tubes on Minox and Tasco are both on the SOFT end of the scale and crush easily at less than 25 inch pounds.

Thanks,

The caps? I believe about 22 inch pounds. 25 inch pounds base to action.

Also, people should realize the importance of "bedding" the base to the action, so as not to stress the action, or the scope. I have never had to lap any Farrell rings because his tolerances are second to none. I have never had 1 ring mark, on any scope that was removed from Farrell rings while using his base also. All good !


Just installed a set of Farrell rings.
Instructions say:
50-55in/lbs for ring to base screws
15-20in/lbs for ring cap screws

Not a big difference on the base, but is different.

Maybe this is a dead thread, but here's some recent torque info.

Tikka T3 Stainless 30-06
Vortex Viper HS 2.5-10, 30mm tube
DNZ Game Reaper one piece

DNZ package says 25 in/lbs.

The guy at DNZ says 30 in/lbs for both base and rings for this combination, no Loctite.

I took the middle road:
-25 in/lbs. all screws (4 in base, 2 in each ring)
-Blue Loc-tite

Here's the current DNZ FAQ page link:  http://www.dnzproducts.com/faq/

Hello all. New to the forum. Just received my new SS 10X42MQ. I have read and watched numerous reviews on this optic. Needless to say, when it arrived and I inspected it, I was very satisfied with the quality. I assembled the sun shade and Butler Creek caps onto it. Everything fit perfect except for the rear cap, which sets quite far in on the focus adjustment. Minor, in my opinion, as I will simply adjust focus for my eyes and reinstall cap. What I was disappointed in, however, was the picatinney rail installed from the factory on my Marlin XS7VH. When I attempted to install the SWFA medium height scope rings, they would not set down into the recoil lug portion of the base. This worried me. The first thing I did was measure the screw shank on the bases. A perfect 0.196 width. (as expected) I next measured the recoil slots on Marlin's rail. What I found were slots machined to only 0.146 in width! Far from the 1913 Picatinney specs which are 0.206 +.008. An online search for bases to fit the Marlin proved unsuccessful. All was not lost though. I removed the rail and clamped in a vise with aluminum jaw covers, filed the appropriate slots to the necessary width, assuring to maintain accuracy by measuring every 5 file strokes. Process was tedious and time consuming, but successful. I then continued with mounting. Scope aligned perfectly, medium rings were correct choice. (proper measuring before ordering is important). The dimensions on scopes and rings is invaluable. Thank you SWFA for making these available on your site.

I do have one question. In the future, are aftermarket bases for the Marlin X7 series of rifles going to be made available?  The rifle , as it comes from Marlin is less than suitable for long range shooting. However, the action, trigger and barrel(heavy barrel) are suitable. I am positive I can turn this inexpensive rifle into a fairly accurate piece of equipment. May be a bit of a challenge, but good bases would help. (I do have a laminate thumbhole stock ordered for it)

 Thanks for listening to my ramblings. I look forward to the comments from everyone. Maybe I'm a bitLoco.LOL

I apologize for posting this in torque specs. I was looking through the posts to verify I had torqued the screws on mine correctly. I thought I had moved to a different forum on scopes in general. Oops.

Welcome to Optics Talk. 

Your rail was Weaver and the rings were Picatinny, or the rail was out of spec?

I believe the base that Marlin uses is made by Weaver. That would explain the difference in recoil slots, even though I thought all rails built of that design were standard on dimensions.

Yes, it is Davenport. Home of 97X and Dwyer and Michaels in the mornings. Still getting settled in here. Used to being out in Cochise County, Arizona the last 34 years. Had plenty of places for extreme long range shooting. Going through a bit of a challenge here to find ranges with enough distance. Longest found in Milan is 600 yds.

Cool. Small world. I was born up in Woodstock, Il., grew up in a little town called Wonder Lake. Went into the Army when I was 17. Moved to Arizona when I got out. Nice to be back in the Midwest.
