Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact dimensional and material specifications, ensuring the washer seats correctly under load without deforming or backing out.
- Exact Assembly Fit — Engineered to match the original hardware profile, this washer installs directly in place of the factory component with no rework or sizing adjustments needed.
- Broad Cross-Machine Compatibility — A single verified part number covers floor saws including the FS5000D, FS6600D, FS7000D, and FS8400D; power packs PP3030, PP2525DS, and PP2525DTR; the CRT36 power trowel; and MS510, MS510G, and MS610 tile and masonry saws.
- Fastener Integrity Under Operation — A correctly fitted washer distributes clamping load evenly across the mating surface, protecting threads and preventing fastener movement during the vibration and torque loads common to cutting and compaction equipment.
- Verified OEM Part Number — Cross-reference 539990250 against your machine's parts diagram to confirm the correct position before installation, particularly given the wide range of compatible models.
A washer functions as a load-distributing hardware component placed beneath a bolt head or nut to spread clamping force evenly across the mating surface. In construction equipment subject to sustained vibration — such as floor saws and power cutters — washers play a critical role in maintaining joint integrity and preventing fastener loosening over time. When a washer is missing, undersized, or worn, the fastener can work loose or damage the surrounding material, leading to misalignment or mechanical failure at the joint.
