Hex head screw for Liebherr 112ECH

The hex head screw 406290401 is a mechanical fastener used to join components within the Liebherr 112ECH tower crane. It provides a secure connection between structural parts, allowing for the transmission of forces across assemblies such as tower segments, the jib, or counterweight systems. The hexagonal head design allows for the application of specific torque levels during installation to ensure a firm connection.

This component is compatible with the Liebherr 112ECH 8-43024 tower crane. It is manufactured to meet the dimensional and thread specifications required for structural integration in this model. Proper installation of this fastener is necessary to maintain the structural integrity of the crane during operation.

Hex head screws function as the primary means of joining heavy steel sections in cranes and other heavy machinery. By providing a high-strength connection, they resist the shear and tensile forces encountered during lifting operations. These fasteners are designed to be tightened with standard tooling, ensuring that structural joints remain stable under load and operational vibration.
