    Fill gaps up to 0.01" to secure unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies. These retaining compounds begin to harden once coated surfaces are pressed together, blocking exposure to air.
    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.

    Threadlockers

    Image of Product. Front orientation. Threadlockers. Threadlockers, Bottle.

    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.
    Low Locking Strength—Often used in setups that require frequent disassembly, these threadlockers are easily released with the turn of a screwdriver or L-key. They give fasteners additional hold to keep them secure against light shock and vibration.
    Medium Locking Strength—Strong enough for most applications, these threadlockers hold firmly until you break their bond with a combination or ratchet wrench.
    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.
    Thick Liquid—Fill larger gaps than thin liquids, so they're best for coarse or worn threads.
    Military Specifications Met—Mil. Spec. threadlockers are manufactured and tested to strict U.S. military standards.
