LOCTITE Threadlockers

Threadlockers are a strong alternative to mechanical locking devices. Whether permanent or removable, they can lower repair and manufacturing costs by preventing fastener loosening, corrosion and seizing of parts.

Our Threadlocking Products

LOCTITE threadlocking products prevent self-loosening and prevent loss of clamp load due to vibration and shock loads. They are easy-flowing liquids which completely fill the gaps between mating threads. When used to assemble threaded fasteners, LOCTITE threadlockers secure threaded assemblies and eliminate corrosion by creating a unitized assembly.

LOCTITE threadlockers are single-component liquid and semi-solid adhesives. They cure at room temperature to a hard solid thermoset plastic when applied to metal fasteners and in the absence of air. The adhesive completely fills the gaps between mating threads to lock threads and ensure consistent clamp loads.
