Star washer for Terex PT30

The 0303-099 star washer serves as a specialized fastening component within the cab assembly, specifically for the ROPS structure of the Terex PT30 model with serial numbers DTA 05001 and higher. Featuring both internal and external teeth, this washer provides a secure interface between fasteners and mounting surfaces. It is engineered to maintain tension on bolted connections, helping to prevent hardware from loosening during the operation of the machine.

This component is compatible with the Terex PT30. Star washers are utilized in various mechanical systems to increase friction between the fastener head and the mating surface. By biting into both the material and the fastener, the teeth create a locking effect that resists rotation caused by vibration and mechanical movement. This ensures that structural connections within the cab remain tightly secured throughout the service life of the equipment.
