Description
Overview:
The Fixing Nut M8 L/H is a genuine Hitachi/Hikoki part for securing cutting attachments on compatible brush cutters, including the Hikoki TBC-230 and TBC-230D. It uses a left-hand (reverse) thread to resist loosening under normal rotation, helping keep blades and heads safely fastened during use. Manufactured from durable steel with a standard hex profile, it is built for reliable service in outdoor and site conditions. Sized to M8 for a precise fit on the intended spindle, this nut is a direct replacement for OEM 6689075 and replaces several earlier references. It is suitable for routine maintenance and repairs by tradespeople, grounds teams, and home users who need a correct-fit fastening for their Hikoki/Hitachi brush cutter assemblies.
