Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Husqvarna's exact 5/16" specification, delivering the correct bearing surface area and material thickness for proper load distribution across fastened assemblies.
- Drop-In Hardware Replacement — This washer seats directly onto standard 5/16" fastener hardware with no rework required, restoring the original clamping and load-spreading geometry of the assembly.
- Broad Saw Compatibility — Fits the FS4600G and RS8500D floor saws and the MS355, MS355G, MS510, and MS510G tile and masonry saws, covering a wide range of Husqvarna Construction cutting equipment.
- Protects Mating Surfaces — A correctly sized washer prevents fastener heads and nuts from pulling through or damaging the material around the mounting hole, maintaining the structural integrity of the assembly over time.
- Verified OEM Part Number — Ordering by part number this part ensures you receive the exact Husqvarna-specified component, eliminating guesswork when sourcing hardware for these machines.
A flat washer serves as a load-spreading interface between a fastener — such as a bolt head or nut — and the surface it bears against. By distributing clamping force over a wider area, it prevents the fastener from embedding into or deforming the material around the hole, which is especially important on the high-vibration assemblies found in floor saws and masonry saws. When a washer is missing, undersized, or worn, fastener joints can loosen prematurely under operational stress, leading to misalignment or accelerated wear of surrounding components.
