Precision washer for Terex HC230

The precision washer, identified by part number 4006 204 00, functions as a fastening element within the mechanical assemblies of the Terex HC230 crawler crane. It is positioned beneath the head of a bolt or nut to distribute clamping load across a wider surface area, which helps protect the underlying material from localized pressure damage during tightening. This component also serves as a spacer to compensate for surface irregularities within the machine structure.

This washer is specifically dimensioned with a thickness of 2.3 mm, an outer diameter of 41 mm, and an inner diameter of 5.2 mm. It is engineered to maintain structural integrity under the compressive forces found in heavy equipment operations. The component is compatible with the Terex HC230 model.

Washers are used in mechanical systems to provide a stable bearing surface for fasteners. By increasing the contact area, they prevent the fastener from sinking into the material and help maintain the required tension in bolted joints, which is necessary for the secure operation of heavy machinery assemblies.
