About Structural Adhesives

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.

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.

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.

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.
