DHS Equipment stocks this part as an authorized Multiquip OEM supplier, so you can order with confidence that you're receiving the correct component for your machine.
Key Features
- OEM-Grade Material and Dimensional Accuracy — Manufactured to Multiquip's specification for correct load distribution across fastener joints, preventing surface damage and fastener loosening under vibration.
- Drop-In 3/8 In. Fit — Sized to seat directly onto 3/8 in. fasteners without filing or shimming, maintaining correct bolt torque and clamp force as designed.
- Broad Fitment Across Roller and Pump Lines — Confirmed for V303E, R2000H, AR14H, V305EH, V305EK, C30HDNI, and C30HDGA equipment, covering both walk-behind and ride-on roller models as well as Mayco concrete pump applications.
- Vibration Resistance — On compaction and pumping equipment subject to continuous mechanical vibration, a correctly specified washer maintains joint integrity and prevents fastener backing out during operation.
- Genuine Multiquip OEM Part — Carries part number 504679 and is sourced through authorized Multiquip distribution, confirming authenticity and traceability for fleet maintenance records.
A flat washer serves as a bearing surface between a fastener head or nut and the material being clamped. By spreading the clamping load over a wider area, it protects the mating surface from deformation and helps the fastener maintain its specified torque over time. On equipment like rollers and concrete pumps — where vibration and mechanical stress are constant — using the correct washer ensures that bolted assemblies stay tight and aligned. A missing, undersized, or incorrect washer can allow fasteners to work loose, leading to misalignment, accelerated wear on surrounding components, and potential structural failure at the joint.
