Flat washer for Terex HC230

The flat washer with part number 4006 577 05 is a fastening component utilized in the Terex HC230 crawler crane. It is designed to be placed under the head of a fastener, such as a bolt or nut, to distribute the clamping force over a larger surface area. By spreading this load, the washer helps protect the contact surface of the machine components from deformation during the tightening process.

This component is compatible with the Terex HC230 model. It ensures that bolted joints remain stable and properly tensioned within the machine's various structural and mechanical assemblies.

In heavy machinery, flat washers perform the general function of providing a smooth bearing surface for rotating fasteners and preventing the fastener from sinking into the material. They also act as spacers in specific mechanical configurations to maintain correct alignment between joined parts, helping to preserve the integrity of the connection under operational loads.
