As a direct OEM replacement, this spring washer is built to Husqvarna's exact tolerances, ensuring the correct load-bearing and locking performance the original assembly demands. Compatible machines include the FS4800D, FS5000D, FS7000D, PG680, PG820, PG400, and many more models across multiple equipment families. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM Spring Tension Spec — Manufactured to Husqvarna's original elasticity and load rating, delivering the correct clamping force and vibration resistance this fastener assembly requires.
- Direct Drop-In Replacement — Matches the original washer's diameter, thickness, and spring profile so it seats correctly without any rework to the surrounding hardware.
- Wide Equipment Compatibility — Fits FS series floor saws, PG series floor grinders, the PP518 power pack, BS series floor scrapers, and the EBE500 steel blaster — cross-reference part number 735116401 against your parts diagram to confirm your specific model.
- Fastener Integrity Under Load — A functioning spring washer maintains consistent bolt tension under vibration and cyclical loading; a worn or flattened washer allows fasteners to back out, leading to loose assemblies and accelerated component wear.
- Genuine Husqvarna OEM Quality — Sourced directly from Husqvarna's authorized parts program, ensuring material grade and dimensional accuracy consistent with the original equipment build.
A spring washer is a hardened, curved or helical fastener component placed beneath a nut or bolt head to maintain clamp load under vibration. As the joint settles or vibrates during machine operation, the washer's spring tension compensates, preventing the fastener from loosening. In heavy construction equipment like floor saws and floor grinders — which generate significant vibration during cutting and grinding passes — maintaining proper fastener torque is critical to keeping structural assemblies tight and mechanically sound. When a spring washer loses its temper or collapses flat, bolt tension drops and connected components can shift, wear unevenly, or fail prematurely.
