Hexagonal nut for Liebherr LTM 1160-2

The 411900208 hexagonal nut is a specialized self-locking fastener used within the assembly of the Liebherr LTM 1160-2 mobile crane. This component features a non-metallic insert, which is characteristic of the DIN 985 specification, designed to prevent the nut from loosening under operational conditions. The part is defined by a metric thread diameter of 4 mm and is manufactured to the 8A2C resistance and finish standard.

This fastener is compatible with the Liebherr LTM 1160-2 crane model. It serves as a critical connection point in various mechanical assemblies where maintaining torque and preventing vibration-induced loosening is required for the integrity of the machine. The self-locking design ensures that the connection remains secure throughout the dynamic operation of the crane.

In heavy machinery, self-locking nuts are used to secure bolted joints that are subject to constant movement or vibration. By providing a consistent locking force, these nuts maintain the alignment and stability of connected components, reducing the need for frequent manual checks and tightening of hardware across the machine's various systems.
