Genuine Maruyama Head/Cutting Disc Locking Nut

Part Number: 225893
Product Description

The genuine Maruyama part number 225893 is a high-precision replacement nut designed specifically for the cutting head assembly of professional brushcutters and string trimmers. This nut D.M8x1,25 Left is essential for ensuring the secure and stable locking of the blade, cutting disc, or trimmer head onto the gear case shaft, preventing dangerous loosening caused by heavy vibrations and high rotational speeds during operation.

Manufactured from high-tensile steel, it features a heavy-duty thread (typically left-handed, specific to counter-clockwise rotary systems) engineered to resist mechanical wear, corrosion, and accidental impacts with stones or soil.

•     Component Type: Flanged nut / Locking nut for trimmer head and blade
•     Main Compatible Model: Maruyama BC2300RS brushcutter (and other models within the same mechanical range).

Key Features & Benefits

•     Certified Safety (OEM): As a genuine Maruyama spare part, it complies with the strictest safety standards to prevent the cutting attachments from detaching while in motion.
•     Heavy-Duty Threading: The thread profile is optimized to withstand frequent mounting and unmounting operations without stripping.
