Re: Are you serious ? No frickin way . . . Lube the pic rail (or other type of base) to the scope rings ?!?!?!

Yes, you absolutely can over-torque fasteners by wet installing to a spec for dry install. Friction reduces the torque needed to reach a certain clamp load, which is all you're trying to do. does wet mounting ring or base increase torque enough to matter though? Your question is relevant to the base to the rifle, and the rings to the base and not ring to ring. Correct? I’m more curious as to using loktite/paint etc in screws them selves. Everything has a break point but does wet vs dry screw torque matter in rings? More asking on the integrity of ring to ring and base clamp screws/bolt. The wet rail isn’t an integrity issue, you aren’t going to crush the rail. I have seen other base clamps break at 45lb dry and wet(torque spec per CS was 25-30lbs) . Not the screw, and not the female threads on back side but base clamp it’s self , wet/dry torque difference was to minimal to measure Example: I have rings that come with threadlocker, torque spec is 45base /25lbs top and since it comes with threadlocker/loctite/paint etc that would be a wet spec, but they have said it doesn’t matter. Have other rings from another company that are 68in base 25ring, you call them and ask them dry or wet, they say spec is spec and the same. So is there a significant difference in wet vs dry torque specs on scope rings components them selves, my idiot testing from assuming torque specs on some lower torque spec rings says no, but that’s hardly a large sample size. .

You mean lubing the rails? I don't have an analysis to confirm, but I don't think that would impact clamp force in a meaningful way. Sorry On screw threads, specifically.

Yes anytime you lube the screw threads, it's going to decrease the torque required to accomplish the same clamp force.

Patriot07 is correct about above.
I think the scope of the original issue is friction from rings to base on a picatinny rail not allowing the rings to seat properly at the correct torque spec. Then when dropped etc (additional force) they do seat, causing a shift in windage.

Yes but to a degree that it actually matters?
