    Bottle

    The most commonly used threadlockers, these liquids prevent loosening due to vibration, bending, or improper torque. You only need a few drops to evenly coat threads. As you twist parts together, exposure to air is blocked and the threadlocker begins to harden.
    Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes; and cadmium and zinc coatings.
    High Locking Strength—Keep fasteners firmly in place in motors, pumps, and other applications subjected to heavy shock and vibration. Breaking the bond of these threadlockers requires a propane torch, heat gun, or induction heater. As a result, they shouldn't be used in setups that you disassemble often.
    Thin Liquid—Seep into tight spaces better than thick liquids, so they're best for fine threads.
    Military Specification—Mil. Spec. threadlockers are manufactured and tested to strict U.S. military standards.
