Hexagon bolt for Liebherr LTM 1070-4.1

The hexagon bolt, part number 11 64 48 99, serves as a fastener for securing various structural and mechanical assemblies within the Liebherr LTM 1070-4.1 crane. This component is manufactured to the ISO 4017 standard, which defines a fully threaded hexagon head configuration. The bolt has a nominal thread diameter of 6 mm and a length of 20 mm, with a strength class rating of 8.8.

This fastener is utilized across the Liebherr LTM 1070-4.1 to maintain the integrity of connections between panels, covers, brackets, and other mechanical elements on the chassis and superstructure. The 8.8 strength class provides the necessary tensile characteristics required for applications subject to the static and dynamic loads typical of crane operation.

Hexagon bolts are used throughout heavy machinery to provide secure, removable joints between components. By applying the correct torque during installation, these fasteners ensure that structural elements remain properly aligned and fixed in place, preventing movement or vibration within the assembly. Proper selection of fasteners based on thread pitch, length, and material strength is essential for maintaining the mechanical configuration of the crane systems.
