I would not exceed the max torque for the respective screw size.

6-48 no more then 20 In/lbs
8-40 no more then 40 in/lbs

Reduce the above when screw in installed in aluminum by 30%

Now that said I've never used a torque wrench on scope bases or rings. A firm hand with the proper wrench and a drop of lock tite does the trick.

I don't recommend loctite on ring screws, and I rarely use it for base screws. Provided both screw and hole threads are clean, a drop of oil and the right amount of torque should hold things together.

BTW, depending on the person, a firm hand and proper wrench develops considerably more torque than is needed and is why the use of a torque wrench wouldn't be a bad idea. Big Grin

Thanks.

Well the torque wrench is a good idea then. I for one have developed a feel over the years but I do own three torque wrenches and I'm not afraid to use them when needed.

If you ordered the Wheeler it comes with a little guide in it.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.



What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

tin can, I read this somewhere that I gave credence to so I go like this

rings to scope 15-20 inch/lbs

rings to base 20 inch/lbs

base to rifle 25 inch/lbs

action screws 60-65 inch/lbs

somewhere else I read that depending on screw size the numbers were similar, maybe a little less typically, could have been from Leupold site....just can't remember

The torque spec vary and you should check with the manufacturer for their recommendations. Scope rings are usually 15 in/lbs. My Nightforce rings to base torque is 68 inch/lbs. The bottom line is that there can be a lot of variation on rings to base. I use a Brownell's Torque handle and always check with the manufacturer first.

I did a bit of sleuthing on this and apart from tactical type mounts most seem to recommend:
bases to receiver- 12-15 in/lbs
ring halves - 12-15 aluminum, 15-20 steel

I recently tightened a Burris Zee bases to a weaver mount with 45in/lbs and felt like that was maxing it out...

I know that Leupold Mark 4 rings have a spec of 65 in/lbs for the ring to base bolt. They have been known to crack at that setting.

as a follow up:
Leupold bases to action - 14in/lbs (Brownells has these figures)
Weaver (email correspondence with Weaver) - aluminum bases to action 12-15 in/lbs
