Key Features
- Genuine OEM Hardware Spec — Manufactured to the original Multiquip specification, delivering the correct dimensions, material grade, and load-bearing surface area for each listed application.
- Cross-Platform Compatibility — A single OEM part number covering ride-on rollers, concrete pumps, stationary mixers, and power buggies — confirming correct fitment across all listed models.
- Confirmed Fitment — Verified for the AR13D, AR14H, LS300G, LS300P, LS600P, PRO12, PRO12E51, PRO12E53, PRO20, WTB-16, and WTB-16PD.
- Proper Load Distribution — A correctly sized flat washer spreads clamp load evenly across fastened surfaces, protecting mating components from damage caused by under- or over-torqued fasteners.
- Direct Drop-In Replacement — Sized to the original 1/2" standard, this washer installs alongside existing fastener hardware without modification or sizing adjustments.
A flat washer distributes the clamping force of a bolt or nut evenly across the surface it contacts, preventing the fastener from pulling through or damaging the material beneath it. In heavy-duty equipment applications — whether on a roller frame, pump housing, mixer assembly, or buggy chassis — using a washer of the correct diameter and thickness ensures that bolted connections maintain proper torque retention over time. A missing, deformed, or incorrect washer can allow fasteners to loosen under vibration, which may lead to structural movement or accelerated wear at the connection point.
