It goes by materials used and fastener type.... most manufacturers have their own reccomendations..... pretty much standard for bases is 25 inch pounds.... rings 15 inch pounds..... action screws I have heard mixed numbers.... You can use any general torque chart if you know the thread size of your fasteners.....

^ Yup. Base screws are usually ~25 in-lbs, ring screws are 15-20 in-lbs, depending on manufacturer, and action screws are usually anywhere from 40-95 in-lbs, depending on the action and stock.
Wow... 95 inch pounds?... That's a lot of torque!
Interesting thread, learn something new everyday. Never thought of torqueing the screws on a gun to specific weights. Makes sense when you think about it.
For the last 40 some years I have done it all by feel. Kind of like setting a toilet to the floor. To tight and you crack the toilet, to loose it leaks. It's gotta be just right.
What do these torque wrench's for guns look like? anybody got pictures. Since I have just about every other tool known to man I might as well look into getting one of these as well.

torqueing the action screws on my cz452 makes a big difference in accuracy. I've settled on 20lbs for mine, others are between 14 and 26 , just puttin it out there. CZ guys have been doing this forever with great results.
For the guys that were in this thread that bought a couple of the ones I have on in the EE the instruction manual can be found here.... may also be of interest to folks wondering how these work...

Yeah, it is, but that's what Ruger recommends on their Hawkeye rifles. If I'm using a good, stiff composite stock that is pillar and glass bedded, I like to stay somewhere around 55-65 in-lbs. On a laminate stock that isn't pillar bedded, I'll usually go around 45-55 in-lbs and on a regular wood stock I'll use about 40 in-lbs. Unless the manufacturer recommends otherwise.

They look like a fat-handled screw driver
Look up Borka, Wheeler FAT wrench, and it sounds like Superbrad may have some sort of torque driver for sale.
Used a Snap on yesterday on my CZ varmint 22, went with 20lbs as that seems to be a good average from the boys at Rimfire central. This unit looks to me like it is a fairly expensive piece relative to the Fat or Weaver products. FS
It's a tool... and like anything, you get what you pay for.... that being said, I wager even torquing with a cheap one is better than not torquing at all.... as long as the cheap one is consistant.......
The Uticas I have I bought for a shop and as such I bought the best.... now, if I was just using them at home I am not sure I would have paid that much to torque my rifles... but you never know... all depends on funds at hand....
Bumped my for sale thread last night and got me thinking, has anyone ever torqued a saddle mount before?... Stands to reason that if you would torque bases you should torque a saddle mount also... Anyone have the specs?
