Multiquip EM508346 Special Washer C30HD

The Multiquip EM508346 Special Washer C30HD is a genuine OEM replacement designed for the AR13HA/HAR, AR13H, and AR13HC asphalt ride-on rollers. As a factory-sourced component, EM508346 is manufactured to the exact dimensional and material standards specified for these machines, ensuring a correct, consistent fit every time. DHS Equipment supplies this part direct, so you can be confident you are receiving an authentic Multiquip component backed by the original specification.

Key Features

• Genuine OEM Material Grade — Manufactured from C30HD-grade material to meet the hardness and load-bearing demands required at the specific mounting point on your roller.
• Exact Dimensional Match — Produced to the same tolerances as the original hardware, seating flush against mating surfaces without shimming or adjustment.
• Confirmed Fitment — Compatible with AR13HA/HAR, AR13H, and AR13HC series Multiquip asphalt ride-on rollers.
• Protects Fastener Integrity — A correctly spec'd washer distributes clamping load evenly, preventing fastener pull-through, surface galling, and premature loosening under vibration.
• Direct OEM Source — Sourced straight from Multiquip, not an approximation — the part number EM508346 matches exactly what was installed at the factory.

A special washer like the EM508346 serves a critical load-distribution function at its fastener joint, spreading clamping force across a wider surface area to protect both the fastener and the material it bears against. On vibratory roller equipment, where constant mechanical vibration cycles are transmitted through the frame and drum assembly, hardware integrity is essential — an undersized, worn, or incorrect washer can allow fasteners to loosen progressively, leading to joint failure or structural damage. Replacing a worn or missing washer with the correct OEM-spec component restores the clamping assembly to its designed operating condition.
