Used the Search but had not luck.

I am using individual rings to mount a scope.  I am looking for recommended torque specs for both the "base to rail" and "ring to base".

I am more familiar with bolt guns and those values. Just can't find a thread on this....I am sure their is one.

Thanks,

I use the torque values the manufacturer of the mount lists in the instructions for the mount.

Unfortunately I don't have any of that.  I did not know if there were generally accepted guidelines especially for base to rail considering both are aluminum.

Want it tight enough but don't want to f anything up.

torque specs are on a chart,
it is based on the grade of the bolt
and the size.


The Wheeler torque wrench kit lists:
Base Screws. 30 in lbs
Windage Screws 30-40 in lbs
Ring Screw aluminum rings 10-15 in lbs
Ring Screw steel rings 15-20 in lbs

Thanks.  I will try to identify  the base screw size and go from there.  

Just thought there may be some standard or "rule of thumb" when dealing with aluminum picatinny rails and bases.

Thanks and any other thoughts appreciated.

That's a good general list.  I would go lower on the base screws if the screws are the smaller 6-48 screws though.  More like 20-25 in-lbs depending on how deep the threading is in the receiver.  Also, use BLUE locktite on the base screws only.

The ring screws I would even go up to 17-18 in-lbs on aluminum.  

18-25 on steel rings.   I've even done rings up to 30 in-lbs on heavy recoilers with heavy scopes without marring the scope (gotta make sure the rings are aligned and lapped in if needed).

1/2" nuts on bases get torqued to like 65 in-lbs.

take them to a hardware store or hobby shop and identify them by finding the nut they screw into, then you can look them up on a chart.
