Henkel’s LOCTITE® brand is the trusted choice for engineered, high-performance adhesive, sealant and coating solutions. 

Mechanical locking devices (such as split ring washers, nylon insert nuts, and serrated tooth washers were invented to solve the common problem of loosening that happens in most threaded assemblies). However, the reality is that they don’t “lock” the assemblies and can’t maintain clamp load. These devices often loosen under vibration, thermal expansion, bending, and/or improper torque.

Threadlockers, or threadlocking adhesives, are the solution to this problem. Applied between two mating threads, these liquid threadlocker adhesives secure nuts, bolts, and threaded fasteners in place. They cure to form a strong bond that prevents loosening, ensuring assemblies retain clamp load over time.
