Description
Overview:
The Wave Washer M10 for Hikoki Hitachi grass trimmers is a genuine spare designed to keep fastened assemblies tight and smooth-running under vibration. Made from durable metal with a wave-profile spring design, it applies consistent axial preload around M10 fittings to help prevent loosening and rattle. This washer is used across a range of Hikoki/Hitachi machines, including the CG 40EYA and CG 33EJ, where it supports reliable operation of rotating and housing components. As an OEM part (6695203), it offers a straight swap for worn or missing washers and helps maintain performance, reduce wear, and extend service intervals on trimmers and brushcutters used in domestic, commercial, and landscaping tasks.
