The Husqvarna 542020776 Lock Washer is a genuine OEM fastener component designed for the FS3500E floor saw. Sourced directly from Husqvarna, this lock washer is built to the exact specifications required to maintain secure, properly torqued connections on the FS3500E. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Hardness and Temper — Manufactured to Husqvarna's precise material specifications, ensuring the correct spring tension and bite needed to resist fastener back-off under vibration loads typical of floor saw operation.
- Direct Hardware Match — Matches the exact diameter, thickness, and inside bore of the original fastener position on the FS3500E, dropping into place without any modification to the mounting hardware.
- FS3500E Floor Saw Fitment — Confirmed fit for the Husqvarna FS3500E floor saw; cross-reference 542020776 against your parts diagram before ordering to verify the correct position.
- Vibration Resistance — A correctly functioning lock washer prevents critical fasteners from loosening during high-cycle cutting operations, keeping assemblies torqued to spec throughout the workday.
- OEM Part Number Assurance — Ordering by part number 542020776 eliminates guesswork and ensures the replacement matches the original hardware grade used during Husqvarna factory assembly.
A lock washer sits beneath a fastener head or nut and uses its spring-like or toothed geometry to bite into both the fastener and the mating surface, creating mechanical resistance against loosening. On a floor saw like the FS3500E — where continuous blade vibration and cutting loads are transferred through the machine frame — maintaining proper fastener torque is essential to structural integrity and safe operation. A worn, flattened, or missing lock washer allows fasteners to back out gradually, which can lead to misalignment, component loosening, or more significant mechanical failure if left unchecked.
