Anaerobic compounds, when used with threaded fasteners, serve what purpose?

Anaerobic compounds, when applied to threaded fasteners, are primarily designed to serve as thread locking agents. They function by filling the gaps between the threads of the fasteners and curing in the absence of air. This curing process creates a robust bond that not only secures the fastener in place but also prevents it from loosening due to vibrations or other mechanical stresses.

While anaerobic compounds can provide benefits like sealing properties and some degree of corrosion resistance, their main role in the context of threaded fasteners is to lock the threads securely. This ensures that the components stay assembled under harsh conditions, making them particularly valuable in applications where reliability and safety are critical.
