About Structural Adhesives

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.

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.

Threadlockers

Prevent threaded fasteners from loosening due to shock and vibration. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked. 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.

Threadlockers with medium locking strength require a hand tool to unthread.

Threadlockers with high locking strength require both heat and a hand tool to unthread.

Threadlockers for Drinking Water

Anaerobic threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

2046 is anaerobic, but also hardens if exposed to air to form a dry surface. It does not require primer when used on stainless steel.

Heavy Duty Threadlockers

To withstand demanding, high-vibration applications such as motor and pump housings, these threadlockers have high breakaway torque. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Adjustable Threadlockers

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. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Wicking Threadlockers

Apply these threadlockers on fasteners that are already installedâ€”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 medium locking strength require a hand tool to unthread.

Primers for Threadlockers, Retaining
Compounds, and Acrylic Adhesives

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