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.

While other threadlockers can cause brittleness and cracking, these liquids won’t weaken plastic. They secure nylon, PTFE, and other plastic fasteners.

Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal.

These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

7524A161 is solvent free. If the adhesive hardens in the tube, soften in warm water before dispensing.

Low in chlorine, fluorine, and sulfur, these threadlockers create the best bond with reactive metals, such as titanium. As you twist parts together, exposure to air is blocked and the threadlocker begins to harden.

Make tough, flexible, oil-resistant seals. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing). Note: These sealants are not for use on parts that come into contact with gasoline.

Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

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.

For use in processing equipment that carries large particles _1/16" in diameter and larger, these ceramic-filled epoxies rebuild and repair surfaces exposed to abrasion from particles, such as pump housings, chute linings, and hoppers. The size listed is the combined total of the two parts.

Secure fasteners that are already installed—these threadlockers are thin enough to flow into tiny gaps.

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.

Prevent heat from loosening fasteners with threadlockers that resist temperatures up to 450° F. 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.

For use in processing equipment that carries particles smaller than _1/16" in diameter, these ceramic-filled epoxies rebuild and repair surfaces exposed to abrasion from particles, such as dust collectors, fan blades, and fan housings. The size listed is the combined total of the two parts.

These threadlockers meet NSF/ANSI 61 for securing fasteners in drinking water systems. They begin to harden when you thread coated surfaces together, blocking exposure to air.

Keep fasteners joined at temperatures up to 650° F. Squeeze this paste onto threads and it won’t drip, even when applying to parts installed vertically or overhead. The bond begins to harden when you thread coated surfaces together, blocking exposure to air.
