Hardened flat washer for Terex BT4792

The WAH-31NX000-Y2 is a narrow hardened flat washer used in the fastening assemblies of the Terex BT4792 crane. This component is designed to distribute the load of a bolt or nut across a wider surface area, which helps reduce localized pressure on the mounting surface and protects adjacent machine components from damage during assembly.

This specific washer has an inner diameter of 0.3125 inches and features a zinc-plated finish. The narrow design allows for installation in constrained spaces where standard washers may not fit. It is engineered to maintain its shape under high loads and is suitable for use in connections that experience regular vibration.

Flat washers are used in mechanical systems to provide a smooth bearing surface for fasteners. By increasing the surface area under the head of a bolt or nut, they help maintain consistent clamping force and prevent the fastener from sinking into the material it is securing.
