Usually make/model dependent. User's manual might provide the answer.

There is no one-size-fits-all answer to your question, there are way too many variables.
Check to see what your gun’s manufacturer recommends. Most manuals can be found online with a Google search.

I really need to agree with "Rio" and the above post. Too many variables involved. Are we discussing a carbon fiber stock? A laminated stock? An American Walnut stock with open grain capillaries? Or maybe even a Maple stock with closed pores & tight, grain?
There are some stockwoods that I've dealt with that required "pillar bedding", but only because the open grained walnut, even after and under the glass bedding, could have the open wood capillaries that draw moisture up through the tree to feed the leaves, now being open as they are, ruin the efforts involved with glass bedding only, and have the stock wood under the glass bedding become prone to collapse as the action screws are tightened, even with an 8 year old dried stock blank. That will in most cases change the bedding somewhat and accuracy will, in most cases suffer.
With those type wood stocks I prefer to make and install aluminum pillars that fit between the upper and lower metal, and then assist the bedding to stay consistent with a measured, and consistent torque rating that will maintain the initial accuracy settings involved. So, as a recommendation, I would have folks consider, trying various torque settings on action screws on those action screws until YOU find you have the best accuracy you can obtain with your preferred ammunition, and then don't expect that setting to be compliant with another bullet weight or load combination for that particular caliber, or reloaded value.
Those are just suggestions that have worked well for me over the years. If you feel your method outweighs what I' found, PLEASE, bring your suggestions to light as I hope, most are here to learn and try.

According to Savage the torque on Axis rifles is 35ft lbs, so I have been using that # ever since, I agree with above that I need to check with each manufacturer and each model to verify what I'm doing

Very much something to check OEM spec on. And to go find the readily available internet calculators to convert inch/# & foot/# to N/m and back again.

Be sure to put a little oil on the threads before torquing. The purpose of torquing to a certain value is to exert a certain amount of clamping force via the threaded fastener. If the threads are dry, some of the torque is lost to friction rather than being transferred to clamping force.

Make, model, and caliber dependent. For example, a 10/22 needs a lot less torque than a M77.
I Thats a fair standard for a full size bolt action using 1/4 or similar size bolts.
Smaller screws like a 527 or most .22s and 25 is about as high as ill go.
As others have said tho, torque specs are usually action/stock specific.
Most of my unpillared factory stocked guns are torqued 35 rear, 40-45 front. Pillared and some are torqued to 60-65.

I'd love to see more rifle makers use "torx head screws" rather than the slotted or hex head variety. Driver bits for torx head screws seem to have less tendency to "cam out" like the slotted head screws can do, and even hex head driver bits will often round out the hex socket if the socket is a bit softer than normal and the fit is a bit funky.

Make sure to do so in sequence. Dosent matter exact sequence, just do it the same each time you have it appart.
