Threadlockers

Bottle

Single-Use

Capsule

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 Specification—Mil. Spec. threadlockers are manufactured and tested to strict U.S. military standards.

Reusable Threadlockers

Aerosol

Can

Unlike most threadlockers, these don't need to be applied every time you remove and reinstall your fasteners. Put on a fresh layer once every three to five uses.

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

Thin Liquid—Seep into tight spaces better than thick liquids, so they're best for fine threads.

Thread Sealants

Bottle

These thread sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.

Medium Locking Strength—Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

Extreme-Temperature Threadlockers

Bottle

Extreme cold and heat won’t weaken the bond of these ceramic threadlockers. Able to withstand temperatures from -300° F to 2,100° F, they can be used in equipment ranging from cryogenic freezers to kilns.

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

Thick Liquid—Fill larger gaps than thin liquids, so they're best for coarse or worn threads.

Thread Sealants with PTFE


Cartridge	Bottle

PTFE provides a slippery surface that keeps threads from binding. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.

Low Locking Strength—Sealants with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.

NSF/ANSI 61—To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.

Lubricating Threadlockers

Bottle

Reduce friction to protect threads and ease installation. These threadlockers are often used on large fasteners, which can be prone to seizing. They begin to harden when you thread coated surfaces together, blocking exposure to air.

Thick Liquid—Fill larger gaps than thin liquids, so they're best for coarse or worn threads.

Retaining Compounds for Oily Close-Fitting Parts

Bottle

Even on oily surfaces, these retaining compounds keep their hold. Use them to fill gaps up to 0.015" to secure worn 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.

High Locking Strength—Compounds with high locking strength require both heat and a hand tool to unthread.
