Flat washer for Liebherr LTM 1160-2

The flat washer 420000908 is a standard mechanical component used to distribute the clamping force of a bolt or nut across a broader surface area. By increasing the contact area, it helps prevent damage to the mating surfaces and ensures a more stable connection within the various structural and mechanical assemblies of the crane. This component is manufactured to the ISO 7089 A 6 A2C standard, which defines its flat geometry, its suitability for 6 mm nominal diameter fasteners, and its specific material and surface finish properties.

This washer is compatible with the Liebherr LTM 1160-2 all-terrain crane. It is utilized in multiple fastening points throughout the machine where secure, consistent tension is required for operational stability. Proper installation of these washers is necessary to maintain the integrity of bolted joints and prevent the loosening of fasteners during the operation of heavy lifting equipment.

In heavy machinery, flat washers serve as an interface between the fastener head and the component surface. They function to provide a smooth bearing surface for the fastener, which helps achieve uniform torque during assembly and protects the underlying material from scoring or deformation during tightening cycles.
