Apply these threadlockers on fasteners that are already installed—their thin consistency allows them to flow into small gaps. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Threadlockers with low locking strength adjust easily with a hand tool.

These threadlockers give a secure hold, but can be easily adjusted with hand tools. They can be removed without damaging countersunk fasteners, set screws, and other small fasteners. The thin consistency allows them to flow into small gaps, so you can apply them on fasteners that are already installed. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

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.

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.

Compounds with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.

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.

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

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

Apply this thread sealant stick without a mess. It contains PTFE, which provides a slippery surface that keeps threads from binding. Since the sealant is anaerobic, it doesn’t begin to harden until coated surfaces are threaded together, blocking exposure to air. It has low locking strength, so it prevents threads from loosening due to vibration and can be adjusted without tools. It meets NSF/ANSI 61 for use with drinking water.

PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, remaining pliable enough to self-heal and stop leaks before they start, so they’re often used in high-vibration applications that could cause standard thread sealants to fail. Since they have low locking strength, these sealants can be adjusted without tools.

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

VOC (volatile organic compounds) regulations restrict sales of sealants that cannot be sold to the listed jurisdictions/areas.

Formulated to flow into small spaces, use these sealants between fine threads. Threads coated with these sealants can be installed multiple times without recoating. They have low locking strength, so they prevent threads from loosening due to vibration and can be adjusted without tools. They meet NSF/ANSI 61 for use with drinking water.

Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse threads. Threads coated with these sealants can be installed multiple times without recoating. They have low locking strength, so they prevent threads from loosening due to vibration and can be adjusted without tools. They meet NSF/ANSI 61 for use with drinking water.
