Key Features
- Grade 9 Hardness Rating — SAE Grade 9 specification provides superior tensile strength compared to standard hardware, holding up under the high-load fastener applications found on ride-on trowels.
- Yellow Zinc (YZ) Corrosion Resistance — Yellow zinc coating protects against rust and corrosion in outdoor concrete finishing environments where moisture and slurry contact is common.
- SAE 3/4 Dimensional Standard — Manufactured to SAE 3/4 flat washer dimensions for direct bolt-in installation with existing fastener hardware — no sizing adjustments needed.
- Genuine OEM Quality — Produced to Multiquip's original specifications, ensuring the correct load-distribution profile for the fastener joints on these trowel assemblies.
- Broad HTX and STX Series Compatibility — Confirmed fit across HTX6H, HTXG6DF, HTXD6i, STX6H, STX55J6, STX55Y6, and STXD6i Whiteman ride-on power trowels.
A flat washer distributes the clamping load of a bolt or nut across a wider surface area, preventing fastener heads from pulling through or damaging the material being joined. On ride-on power trowels, where vibration and mechanical stress are constant during concrete finishing operations, using the correct grade and size of washer is critical to maintaining secure connections throughout the machine's structure. A washer that is undersized, too soft, or incorrectly rated can deform under load, leading to loose fasteners and accelerated wear at joint points.
