Key Features
- OEM Material and Dimensional Accuracy — manufactured to Husqvarna's exact thickness, bore diameter, and hardness specifications, so load distribution across the fastened joint is consistent with the original design.
- Drop-In Assembly Fit — engineered to seat correctly on the intended fastener or shaft, aligning with existing hardware without rework or shimming.
- Broad Model Coverage — a single part that fits the DC5500 dust collector and the PG680, PG680RC, PG820, and PG820RC planetary floor grinders, covering a wide range of Husqvarna construction equipment.
- Structural Load Integrity — correct washer sizing prevents fastener pull-through, surface damage, and loosening under vibration — common failure points when an undersized or worn washer is left in service.
- Verified Husqvarna Genuine Part — supplied with Husqvarna's OEM part number 515984101 for straightforward verification against the machine's official parts diagram.
A washer distributes the clamping load of a bolt or nut across a broader surface area, protecting the mating material from deformation and keeping the fastener securely torqued under operational stress. In heavy-duty equipment like floor grinders and dust collectors — machines that run under sustained vibration — an improperly sized or deteriorated washer can allow fasteners to loosen progressively, leading to misalignment of components or accelerated wear at the joint. Replacing a worn or damaged washer with the correct OEM part restores the clamping integrity the assembly was designed around.
