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

To speed cure time on coated fasteners, aluminum, stainless steel, or titanium, apply these adhesive primers before using threadlocker or retaining compound. They also work with no-mix acrylic adhesives.

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. They meet NSF/ANSI 61 safety standards for use with drinking water systems.

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.

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.

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.

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

Apply these thread sealant sticks without a mess. They contain PTFE, which 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. They meet 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.

These sealants have high locking strength, so they work in demanding applications, such as securing mounting studs in motor housings. They also withstand applications with large temperature swings.

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start. Formulated without PTFE, these sealants are less slippery and less likely to result in overtightenting than sealants that have PTFE, making them good for plastic pipe where overtightening could lead to cracks and breaks. They have low locking strength, so they can be adjusted without tools.

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.
