This flat washer, part number 3951900, serves as a component for bracket bolt assemblies in heavy mining machinery. Its primary function is to distribute the clamping load of the nut across a wider surface area, which helps protect the bracket material from deformation and ensures the stability of the bolted joint. This component is designed to maintain the integrity of structural connections where consistent tension is required.
The washer is compatible with large-scale mining equipment, including the Bucyrus 4100XPCAC and 7495HR2, as well as the P&H 4100XPCAC and 7495HR2 models. It is intended for use in high-stress applications such as structural mounts or support systems where secure fastening is necessary. The component is manufactured to meet the specific dimensional requirements for these heavy-duty assemblies.
In mechanical systems, flat washers are used to provide a smooth bearing surface for a nut or bolt head. By spreading the clamping force, they prevent the fastener from sinking into the surface of the joined parts and help maintain the correct preload on the bolt, which is essential for preventing the loosening of connections under dynamic loads and vibrations common in mining operations.
