Key Features
- Genuine OEM Material Grade — manufactured to Husqvarna's original hardness and thickness specifications, providing the correct clamping force and surface contact that an undersized or imprecise washer cannot deliver
- Direct Drop-In Replacement — sized and profiled to seat correctly in the original mounting position with no rework or adjustment to surrounding hardware
- Broad Floor Grinder Compatibility — fits HTC280, HTC510, HTC450, PG280, PG400, PG450, and PG510I floor grinders, covering a wide range of Husqvarna planetary grinding platforms
- Protects Fastener and Mating Surface — distributes fastener load evenly across the mating surface, preventing localized stress, deformation, and premature wear of the components it secures
- Verified OEM Part Number — ordering by Husqvarna article number 585416201 eliminates substitution errors and confirms you receive the correct washer for your specific machine
A washer serves as a load-spreading interface between a fastener and the surface it clamps, ensuring that tightening torque is transferred evenly without concentrating stress on a single point. In floor grinders like the PG and HTC series — which operate under sustained vibration and rotational forces — a correctly fitted washer prevents bolt loosening, surface galling, and fastener pull-through over time. When a washer is missing, deformed, or the wrong size, the fastener assembly loses clamping integrity, which can allow components to shift or work loose during operation.
