The primary function of locking glue in engineering applications is to serve as a specialized adhesive that is applied to screw threads to prevent loosening. This type of glue, often referred to as thread-locking adhesive, is designed to secure threaded fasteners, such as bolts and screws, ensuring they maintain their position under vibration and dynamic loads.

When applied to the threads of a fastener, the locking glue fills the gaps and forms a solid bond that resists movement, effectively preventing the fastener from backing out. This is particularly useful in engineering applications where components are subjected to constant movement or vibrations, as it enhances the reliability and safety of the assembly.

In contrast, while sealants are intended to prevent leaks and lubricants reduce friction in moving parts, these serve different purposes from the thread-locking function. Additionally, bonding agents for wood materials focus on adhesion rather than securing mechanical fasteners, highlighting the specific use of locking glue in maintaining tightness and stability in threaded connections.
