Key Features
- OEM Dimensional Accuracy — manufactured to Husqvarna's exact thickness and bore specifications, ensuring the correct clamping load and surface contact for the fastener assembly it supports.
- Drop-In Replacement — matches the original hardware profile for straightforward installation with no modification to existing fastener hardware or mating surfaces.
- Broad Floor Grinder Compatibility — fits the PG680, PG680RC, PG820, and PG820RC planetary floor grinders, covering both standard and remote-control variants in these series.
- Protects Mating Surfaces — distributes fastener load evenly across the contact area, preventing surface deformation and maintaining joint integrity during sustained grinding operations.
- Genuine Husqvarna OEM Part — sourced directly from Husqvarna's construction equipment parts program, so you can be confident this component meets the same standards as the original assembly.
A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. By spreading the clamping force over a wider area, it prevents the fastener from embedding into or deforming softer material and helps maintain consistent clamping pressure over time. On floor grinders like the PG680 and PG820 series, where vibration and rotational forces are continuous during operation, correctly specified washers are essential to keeping assemblies tight and aligned; a missing or incorrectly sized washer can lead to fastener loosening, accelerated wear on mating components, and potential misalignment of grinding heads or drive assemblies.
