Paste Threadlockers

Stick

Even when applying to parts installed vertically or overhead, these threadlockers won’t drip. Paste stays put whether you squeeze, roll, or dab it onto fasteners. The bond begins to harden when you thread coated surfaces together, blocking exposure to air.

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.

Gel Threadlockers

Stick

With a slower flow than liquids, gel threadlockers cling to fasteners for more controlled application and less mess. They begin to harden when you thread coated surfaces 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.

Medium Locking Strength—Strong enough for most applications, these threadlockers hold firmly until you break their bond with a combination or ratchet wrench.
