Several of the regulars, me included, frequently get questions on torque specifications for bases and rings.  The purpose of this thread is to have one central location that lists as many brand- and model-specific torque specs as possible.

This will be something of a "self-policed" thread, so please provide a link to the source when listing the base and/or ring and their manufacturer-recommended torque specification.

All torques are in "in/lbs" and that is NOT THE SAME as ft/lbs!

And to begin:

rail to receiver: 15in/lbs
rings to rail: 65in/lbs
upper ring half to lower ring half: 15in/lbs

rings to rail (clamp screws): 55in/lbs
top ring half to bottom ring half: 15in/lbs

Talley light-weight allow scope mounts
(specs not listen online, I called, he said it was OK to post these, call to verify if you wish)
base to receiver:20-25in/lbs
ring halves:15-20in/lbs


Warne
(please verify this! I called and was told all screws and bolts are 25in/lbs)
ring halves: 25in/lbs
rings to rail: 25in/lbs



SWFA SSALT
http://www.opticstalk.com/forum_posts.asp?TID=18199&PN=2 - http://www.opticstalk.com/forum_posts.asp?TID=18199&PN=2
(As per Chris Farris II's post, second page, first post)
base to rail: 40in/lbs
ring halves: 18 in/lbs

LaRue Tactical LT-104 QD SPR mount
ring halves: 35in-pounds.
(Verified with a call to Tech Serv, asked them to be sure, talked with 2 people, 35 in-pounds.)

Feel free to post additional specs, this is, by no means, a conclusive list!
Yet.

Thanks for posting RC , we have some stores here that do free mounting and bore sighting so I wind up taking my tool with me to the range to help fix scopes. I have seen scopes moving in the rings and rotating in them. It will help to show beginning shooters something printed on how to and why.  I think some people that are learning to shoot get discouraged and quit when a badly mounted scope keeps changing the point of impact and they blame themselves or the rifle or scope etc.

Can't say for sure about 30mm , but the 1 inch are as follows per the package insert.
 
Upper Ring Halves
   T15 Driver - 20 in/lbs
Side Attach Nut
   1/2" Hex - 65 to 100 in/lbs
 
Hope this helps.

Ken Farrell products are as follows:
 
Rings torqued to base is 55-65 inch pounds
 
Ring tops torqued 15-20 inch pounds
 
Base screws: Front screw 20-25 inch pounds, all other base screws: 25-30 inch pounds
 
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 !

Talley Quick-Detachable System - Steel Rings

No specs supplied with product, but available through Talley:

Talley does not list the torque specifications for their rings on their web site or in the printed matter that accompanies the rings.  I wanted to know what the torque specifications were for the Talley Quick-Detachable Scope Rings made of steel in case they are different that for the lightweight rings.  Called Talley Manufacturing today at  (803) 854-5700 and spoke with Gary, who was very helpful.


Torque on bases may vary based on firearm, IMHO:

I suspect that the torque specification for the bases may vary based on the material from which the weapon's receiver is made, the screw diameter and thread pitch, etc., so I defer to the firearm manufacturer for this information, though Talley may have useful suggestions that differ from my opinion; I did not ask. 


Torque specifications for Tally Quick Detachable Rings in Steel with lever:

- Two screws at the bottom of the rings themselves (not the bases but the ones that hold the 2 sides of the rings together at the bottom, under the plate that lies between the quick detachable lever and the ring base: 25-30 inch pounds

- Two screws at the top of the rings (these hold the 2 sides of the rings together at the top): 20 inch pounds

- Quick detachable level: Finger or hand tight.  For reference, if using screw, 35 inch pounds.

Note that Talley instructions indicate that after the two sides of the ring are placed around the scope, the next step is to install the two bottom screws and tighten completely (to toqque spec and no gap between the rings) before any other installations steps are taken

No gap at the bottom of the ring!

I understand that not following this step is perhaps the most common cause of problems that may arise with these excellent rings.

Anyone know the torque for the 1 piece steel base mount for Rem 700 short action made by Warne Maxima Tactical?  I have searched online all night including Warne's website and no specs are listed.  The instruction only says to firmly tighten them.  I have already installed them without the use of a torque wrench and used blue loctite.  Wondering if I should remove them and start over using a torque wrench that I just got.  I just have a feeling that it's on there too tight.  Using the L wrench it came with, I tightenned it as much as I could per instructions on other websites Badger's instruction in particular.  I then used a gunsmithing screw driver with a t-15 head to tighten it even more, turning about 1/4 turn or so.  I know it has about atleast 40 in/lbs of torque. I used the torwue wrench on it set to 35 in/lbs and watch to see if it will turn it in more and it didn't which indicates that it's over 35 lbs of torque.  SHould I leave it alone or remove it and do again using the torque wrench?  But don't know how much torque to use.

Most bases need 15 in lbs.  35 is pretty tight.

AS I indicated in an earlier post, since you are attaching to the receiver I'd refer to the rifle manufacturer for this information.  A Titanium receiver might have a different torque than a steel receiver.   I'd recommend you check with Remington.  MOst of my rifles specify 12-15 inch pounds, but in addition to receiver metal, screw size and thread pitch come into play.

I suppose that there is some risk that you may have over-torqued the screws just short of failure, which could happen at any time when hunting, etc.  Or not.

If it bothers you, take them off, discard and replace the screws, visually inspect the threads in the receiver, determine from Warne the max torque that their screws are designed for, and ask Remington the spec for their receiver.  Them rest easy and post your findings here!

For the Dakota 76 Safari rifle, Dakota recommends that the Talley bases that Talley makes for Dakota be attached to the receiver at 12-15 inch pounds.

While it's not an optice specification, Dakota recommends that the two action screws be attached until the slotted screws are indexed, or to minimum 65 inch pounds.

With these settings in a synthetic stock with Schmidt Bender or Night Force scopes, my Dakota 76 in .375 H&H shoots the Federal 375H (300g Barnes TSX) into 1.5 inch groups at 200 yards, and 5 inch groups at 300 yards (but the rifle probably does better with a better rifle shot than I).

Subject: RE: Torque specs

Good morning xxx:

The guard screws in the rifle are indexed (slots line up with barrel) and not necessarily set to a torque number.  Technically we would set them at a minimum of 65 in-lbs.

The base screws should be around 12-15 in-lbs.

Hope this helps.

  • Tighten rail mount bolt to 55 inch pounds.
  • Tighten scope ring fasteners to 20 inch pounds.

The smaller screws on the precision matched rings rail mount clamp are also 55 inch pounds. I called them to verify that.

Not to confuse the matter, but I picked up a torque wrench today and the instructions make a distinction between lubed fasteners and non-lubed fasteners.

for example:

10-24 UNC Commonly used on scope base windage screws
lubed fastener  - 40-45 in-lbs
dry fastener      - 65 in-lbs

8-32 UNC Commonly used on scope rings
lubed fastener  - 28-30 in-lbs
dry fastener      - 60 in-lbs

6-32 UNC Commonly used on scope base mounts
lubed fastener  - 18-20 in-lbs
dry fastener      - 35 in-lbs

Is it safe to assume that most or all of the screws we deal with have some oil/loctite or some kind of lube on them? The dry specifications seem way too high. I went over all my guns and tightened the ring-to-base screws and stopped myself at around 45 in-lbs because it seemed like so much torque the screws would start stripping >.<   I think I would be afraid to get all the way to 65 in-lbs unless I was working with steel rings and bases. The cheap $12 rings on my lever action started to make scary creaky noises so I quit at around 40 in-lbs.

As a follow up to my previous post: I just got a TPS base and SWFA rings and cranked the ring-base screws up to 65in-lbs with no issues and no scary sounds of impending failure. Guess you get what you pay for Big Grin

      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

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/ - 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

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.
