The Multiquip EM940358 Flat Washer 10mm ID x 20mm OD ZP is a genuine OEM component designed for Whiteman ride-on power trowels, ride-on power floats, and walk-behind rollers including the HTX6H, HTXG6DF, STX6H, PRX, V30-W2-LD, and V30-W2-R. Sourced directly from Multiquip, this zinc-plated washer meets the exact dimensional and material specifications called for in the original equipment assembly. Confirm EM940358 against your parts manual or serial tag before ordering to ensure a correct match for your machine.
Key Features
- Zinc-Plated Corrosion Resistance — The ZP finish provides a protective barrier against rust and oxidation, extending service life in outdoor and high-moisture jobsite conditions.
- Exact OEM Dimensions — A precise 10mm inner diameter and 20mm outer diameter ensure this washer seats correctly against fastener heads and mating surfaces without shimming or modification.
- Genuine Multiquip OEM Part — Manufactured to the same specification as the original hardware, so load distribution and clamping force remain consistent with the designed assembly.
- Broad Trowel and Roller Fitment — Confirmed for HTX6H, HTXG6DF, STX6H, PRX, V30-W2-LD, and V30-W2-R — covering hydrostatic ride-on trowels, hybrid power floats, and walk-behind rollers.
- Drop-In Hardware Replacement — Standard metric sizing means this washer installs directly into existing bolt assemblies on supported models with no rework to surrounding components.
A flat washer distributes the clamping load of a bolt or nut across a wider surface area, protecting the material beneath from being damaged or deformed when fasteners are tightened. On ride-on trowels and rollers, washers are used throughout structural, drivetrain, and panel assemblies where consistent clamp force is critical to keeping components properly aligned and secure under vibration and continuous operation. A missing, deformed, or incorrect washer can allow fasteners to loosen prematurely or cause surface damage to housings and brackets, leading to more significant repair needs over time.
