Flat washer with raised ball socket for Grove machinery

The 9333101581 flat washer is a specialized fastening component designed for use in Grove mobile cranes. It features an 8mm internal diameter and a raised ball socket profile, which allows the washer to accommodate slight angular misalignments between the fastener and the mounting surface. By providing a uniform bearing area, this component helps distribute clamping forces evenly across the connection point, which is necessary for maintaining the integrity of structural joints and support brackets within the crane assembly.

This part is compatible with various Grove crane models where precise fastener seating is required. The raised ball socket design is particularly effective in applications subject to dynamic loads or vibration, as it helps prevent stress concentrations that could otherwise lead to fastener loosening. During maintenance, this washer should be inspected to ensure it remains in proper condition to support the surrounding hardware. Proper installation of this component is essential for the secure fastening of mechanical systems throughout the crane structure.
