Thread Lockers

Thread Lockers are specialized anaerobic adhesives engineered to secure screws, bolts, nuts, and threaded fasteners against loosening caused by vibration, shock, and continuous mechanical movement. These adhesives cure in the absence of air when confined between metal threads, forming a durable bond that delivers high torque retention and excellent shear strength for long-term assembly integrity.

This collection includes Sonlok® thread lockers, part of the industrial adhesive portfolio from Parson Adhesives Inc. Once cured, thread lockers provide reliable resistance to industrial chemicals, automotive oils, hydraulic fluids, and elevated temperatures—making them well suited for demanding environments. Commonly used across automotive assembly, oil and gas operations, valve and pipe sealing, micro motor assembly, and electrical equipment, these products lock, seal, and gap-fill threaded components to maintain operational reliability.

What Are Thread Lockers?

Thread lockers are anaerobic adhesives that cure between metal threads to prevent fasteners from loosening. They lock and seal threaded assemblies while maintaining strength under vibration and thermal cycling.
