    I'm putting a new scope and rings on a rifle, and a question arose... with aluminum rings and steel screws, should I put anything on the threads? blue or red locktite? some breakfree? or what if anything?
    The rings are Leupold aluminum mark 4 rings, the screws are the normal standard torx screws which I assume are some type of steel compound as I think aluminum screws would strip too easy.
    Its my first time with aluminum rings so I don't want to either snap, strip or seize any of the screws in the rings.

    Thanks in advance for any help.

    I would degrease the screws and the screwholes and make sure they are clean. With the torx screws, you can get them tight enough that you don't need to use loctite. Just get them good and snug and try not to strip out the aluminum when you tighten them.

    BLUE locktite for several reasons.

    First, you don't torque down the rings around the scope until they're almost screw shearing tight, that crushes/destroys the scope. 15 inch pounds (pickle-jar tight) only.

    Second, aluminum has different expansion characteristics than steel; what's tight now may not be after repeated heating, shooting, etc.

    I BLUE locktite all scope screws regardless of ring matl.

    I have used Loc-Tite Blue for over twenty years of mounting scopes and have never had anyones scope or rings fail because they loosened up or fell off the gun.
    Good insurance even when you believe there won't be a problem.
    The stuff works.
