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

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.

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.

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.

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.

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.

For strong bonds, clean and degrease surfaces before applying adhesives.

Mix these two-part epoxy surface fillers to create a strong repair in wet environments or underwater. Use them to repair cracked, worn, and damaged surfaces. Size listed is the combined total of the two parts.

Free of metal particles, these lubricants prevent abrasive wear when used on stainless steel and other sensitive metal. They are NSF registered H1 for incidental food contact. All are white for a clean appearance. Also known as thread lubricants, antiseize lubricants prevent threaded fasteners and close-fitting parts from locking together due to corrosion, contamination, or heat.

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.

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.
