Depends on which stock you have. Some have a full aluminum bedding block others don't. The owners manual for your specific gun usually has the torque spec. Personally I do 40 inch pounds front 30 rear. Then up them 5 inch pounds front then 5 rear, to see what shoots best. I just don't exceed the max specified.

From Sako One owners manual for 4 models.

85 A7 QUAD FINNFIRE II

BARRELED RECEIVER
Remove the barreled receiver from the stock as follows (fig. 13):
1. Make sure that the rifle is not loaded with ammunition.
2. Remove the bolt and the magazine.
3. Open the two receiver fastening screws (A) using a Torx T25 driver.
4. Remove the trigger guard by pulling it downwards.
5. Carefully pull the barreled receiver upwards out of the rifle. On the Sako 85 Bavarian Carbine lift the back of the
barreled receiver upwards and pull backwards (fig. 23).
Installation is carried out in reverse order. Tighten the receiver screws to a torque of 7 Nm (62 in-lb). Make sure to
put metallic recoil block (B) in place into stock and pull barreled receiver backwards before tightening the receiver
screws in order to remove the slack from the recoil lug.
NOTE! On Sako 85 Bavarian Carbine the pin on the barrel must be guided to the corresponding hole in the front
part of the stock and pushed in.
i NOTICE
The pin in the bolt stop is preloaded by the spring. However, it may come out of the receiver, if the components are
handled carelessly.
BOLT
Generally, disassembling the bolt is not necessary. If you have reason to believe that too much oil may have
penetrated the bolt, you should clean it in order to retain its smooth operation. This is particularly important if you
use the rifle in cold or harsh weather. The bolt can be disassembled as follows (fig. 14)

Information from manufacturer is far better than random answers on a forum

For firearms with aluminum trigger guards I torque to 45 in /lbs , with steel trigger guards 65 inch lbs

Thanks for the information guys. Much appreciated. I was able to contact Sako in Finland, and they said that the A7 stocks are torqued to 5Nm, which converts to 44 inch pounds.

Interesting that what they told you on the phone is not the same as what is in their published materials like the owners manual. Did they explain why they are recommending 20 less inch pounds than published? or is there something unique about the model you have?

[trigger7mm]

They just told me that for the particular model I have, the specs call for 5Nm, which equals 44 inch pounds. That came directly from Sako in Finland.

He also said that going above 7Nm, 62 inch pounds, could cause damage to the trigger assembly.
