The Multiquip EM504679 is a genuine OEM Flat Washer 3/8 designed for use across a wide range of Multiquip equipment, including the AR14H, R2000H, V305EH, V305EK, V304, LS450, C30HDG, C30HDGA, C30HDNI, and FS1 series. As a direct OEM replacement, EM504679 is sourced to the same standards as the original hardware installed at the factory, ensuring correct dimensions, material grade, and load-bearing properties. This washer fits multiple machine families — from ride-on and walk-behind rollers to concrete pumps and concrete saws — making it a versatile stocking part for busy fleets and service shops. Confirm your model and fastener location against your parts manual before ordering to ensure the correct application.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the original material and dimensional specification, delivering the correct load distribution and surface protection for the fastener assemblies on your Multiquip equipment.
- Drop-In Replacement — Matches the original 3/8 washer profile exactly, seating correctly against mating fasteners and surfaces without rework or modification to surrounding hardware.
- Broad Multiquip Fitment — Verified for use on AR14H, R2000H, V305EH, V305EK, V304, LS450, C30HDG, C30HDGA, C30HDNI, C30HDNI Zenith, and FS1 models, covering rollers, concrete pumps, and concrete saws.
- Prevents Fastener Damage — A correctly sized flat washer distributes clamp load evenly across the joint surface, protecting threads and mating components from deformation under torque and vibration.
- Critical Fastener System Integrity — On high-vibration equipment such as rollers and concrete saws, worn or missing washers can allow fasteners to back out, leading to loose assemblies and potential component failure during operation.
A flat washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it bears against. By spreading clamping force over a larger area, it prevents the fastener head or nut from pulling through or deforming the mating material, and helps maintain consistent clamp load across the joint. On heavy construction equipment operating under continuous vibration and mechanical stress, maintaining correct washer specifications is essential; an undersized or missing washer can allow joints to loosen prematurely, accelerating wear on surrounding components and compromising the structural integrity of the assembly.
