High-Temperature Threadlockers

Keep threaded fasteners from loosening at temperatures up to 450° F. 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.
Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ACTIVITY after your order ships.
