Description
Overview:
The Locknut M6 is a Genuine Husqvarna fastener used to secure components that are exposed to vibration and shock, such as those on disc cutters, brushcutters and Riders. Made from robust steel, it provides a reliable locking action to help maintain clamping force and prevent loosening during operation. Sized for M6 metric threads (6 mm), it is commonly used across Husqvarna professional and domestic machines, including the 268K and 272K disc cutters. It is suitable for routine maintenance and part replacement where an M6 locking nut is specified. Manufacturer Part Number: 732211601 (also referenced as 732 21 16-01).
