Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional specifications, ensuring the washer distributes load and seats correctly within the assembly.
- Drop-In Replacement — Matches the original profile and hole diameter, fitting directly into the same fastener position without modification.
- Broad AR13 Series Fitment — Compatible with AR13D, AR13H, AR13HA, AR13HAR, and AR13HC asphalt ride-on roller variants.
- Protects Mating Surfaces — Proper load distribution across bolt and nut faces prevents fastener pull-through and surface deformation during high-vibration roller operation.
- Correct Part, First Time — Using Multiquip part number 508427 ensures you receive the right washer for your specific AR13 series machine, avoiding mismatched hardware that can compromise joint integrity.
A flat washer serves as a load-distributing interface between a fastener — such as a bolt head or nut — and the surface it clamps against. By spreading clamping force over a wider area, it prevents the fastener from pulling through or damaging softer materials and keeps joints properly torqued under repeated vibration. On ride-on rollers like the AR13 series, where continuous vibration and heavy operating loads are the norm, a worn, missing, or incorrect washer can lead to loosened fasteners, accelerated wear on mating components, and eventual mechanical failure at critical connection points.
