Bolt washer for Terex HC230

The bolt washer, part number 0857 195 UA, is a fastening component engineered for the Terex HC230 crane. It is installed beneath the head of a bolt or nut to distribute the clamping load over a wider surface area. This distribution reduces localized pressure on the mating parts and helps maintain the integrity of the bolted joint during machine operation.

This specific washer is compatible with the Terex HC230 model. It is designed to fit standard fastening assemblies where secure tensioning is required to maintain structural stability. By providing a uniform bearing surface, it assists in preventing the loosening of connections that can occur due to the operational vibrations and mechanical loads typical of heavy crane equipment.

In heavy machinery, washers function by protecting the surface of the component from damage during the tightening process. They also provide a consistent seating surface for fasteners, which is necessary for achieving and maintaining the correct torque specifications. Regular inspection of these components is a standard part of maintenance procedures to ensure that all structural connections remain secure and properly fastened.
