329900304 Thickened flat washer XCMG XDE130 Electric driving dump truck spare parts

The 329900304 thickened flat washer solves the problems of traditional flat washers, such as insufficient thickness, easy deformation, and poor pressure resistance. It is compatible with XCMG excavators, loaders, and other models, used for bolted connections in engines, frames, and other components, suitable for harsh working conditions such as mines and construction sites. This product conforms to XCMG original factory and GB/T97.1-2002 standards, using Q235/304 base material, cold-forged, deburred, and galvanized. It has a thickness ≥3mm, a hardness of 200HV, a large bearing area, disperses bolt preload to prevent deformation of the connection, withstands temperatures from -40℃ to 100℃, is corrosion-resistant and compression-resistant, precisely sized to fit bolts and nuts, is easy to install and can be directly replaced, extending the service life of the connection.
