The Multiquip 50145900 Flat Washer 10.5 is a genuine OEM component designed for the MVH508DZ reversible plate compactor and RW1404, RW1404MR, and RW1504HF RAMMAX roller series. As a direct OEM replacement, this washer is manufactured to the exact material and dimensional standards Multiquip specifies for these machines. Stocking the correct hardware on the shelf means faster turnaround when scheduled maintenance or unexpected repairs come up. Confirm your model number against the fitment list before ordering to ensure you receive the right part the first time.
Key Features
- OEM-Grade Material Consistency — Manufactured to Multiquip's exact thickness and hardness specifications, ensuring proper load distribution across fastened joints without deforming under torque.
- Drop-In Hardware Fit — The 10.5 mm bore matches the original hardware configuration, allowing straightforward installation without reworking the mounting surface or fastener stack.
- Broad Fitment Coverage — Compatible with the MVH508DZ plate compactor and the RW1404, RW1404MR, and RW1504HF roller models, covering multiple Multiquip equipment families with a single part number.
- Fastener Joint Integrity — A correctly sized flat washer spreads clamping load evenly across the contact surface, preventing bolt-head pull-through and maintaining the clamping force that keeps critical assemblies secure during operation.
- Genuine OEM Sourcing — Supplied as a factory-authorized Multiquip replacement part, so the specification, finish, and dimensional tolerances match what was installed at the point of manufacture.
A flat washer serves as a load-distribution interface between a fastener head or nut and the surface it clamps against. By spreading clamping force over a wider area, it prevents the fastener from pulling into or damaging the base material, which is especially important on equipment subject to continuous vibration — such as plate compactors and vibratory rollers. When a flat washer is omitted, undersized, or worn thin, fastener joints can loosen progressively under machine vibration, leading to misalignment or component separation in assemblies where consistent clamping force is critical.
