The Multiquip 512193 Flat Washer 3/8" Large is a genuine OEM replacement designed for a wide range of Multiquip equipment including the MC12PH concrete mixer, WTB-16 and WBH-series power buggies, and the R2000H static roller. As a factory-sourced component, the 512193 meets the exact material and dimensional standards specified for these machines. Whether you are servicing a power buggy, mixer, or roller, this washer ensures correct load distribution and fastener integrity at the joint. Verify your model against the fitment list — this part is confirmed for the MC12PH, WTB-16PD, WTB-16, WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, WBH21EPA, and R2000H.
Key Features
- Genuine OEM Material Grade — Sourced directly from Multiquip, this washer meets the hardness and surface finish specifications required for structural and mechanical fastening applications on Multiquip equipment.
- Large-Flange Load Distribution — The oversized bearing surface spreads clamping force across a wider area, protecting mating surfaces and preventing fastener pull-through under vibration and dynamic loads.
- Drop-In Replacement — Matches the original 3/8" bore and large-flange outer diameter exactly, seating correctly against OEM hardware without modification to the fastener stack.
- Broad Model Coverage — Confirmed fitment across MC12PH mixers, WTB-16 and WBH-series power buggies, and the R2000H roller, making it a practical stocking item for mixed fleets.
- Vibration Resistance — Correctly sized washers maintain clamp load over time on high-vibration equipment like power buggies and rollers, preventing fastener loosening that can lead to mechanical wear or structural play.
A flat washer serves as a load-distributing interface between a fastener head or nut and the surface it clamps against. By spreading the clamping force over a larger area, it protects softer or thinner materials from being deformed or cracked under torque. On equipment subject to continuous vibration — such as power buggies and compaction rollers — washers also help maintain consistent clamp load by evening out surface irregularities at the joint. When a washer is missing, undersized, or worn, the fastener can work loose over time or damage the surrounding material, leading to joint failure or costly component replacement.
