Washer
Mack

This washer serves as a durable spacer and load distributor in fastened joints, ensuring even pressure distribution and protecting mating surfaces from gouges or indentations. By increasing the bearing area, it reduces the risk of material creep and loosening due to dynamic loads and thermal cycling. The washer type is selected to resist corrosion and galling while maintaining a stable clamping environment. Correct sizing and placement are essential for achieving consistent torque retention and long term reliability in powertrain, chassis, or body assembly applications. Regular inspection guards against wear and ensures continued performance. Source One Parts Center
