Key Features
- Genuine OEM Material Consistency — Manufactured to Multiquip's original material and dimensional spec, so hardness, thickness, and inner diameter match what came off the assembly line.
- Direct Hardware Match — Sized at 1" to drop straight into the same fastener stack as the original, with no shimming, trimming, or adaptation needed.
- Broad Equipment Compatibility — Fits EM12M series mixers, MVH508DZ reversible plate compactors, WM45H/WM45HE/WM45HCE mortar mixers, MC94P/S and MC12PH concrete mixers, V303E rollers, and C30HD-series concrete pumps.
- Load Distribution Where It Counts — A correctly sized flat washer spreads clamping force evenly across the mating surface, protecting threads and preventing fastener pull-through under vibration and operational stress.
- Sourced from DHS Equipment — Sold as an authorized Multiquip OEM part, so the part number EM501299 you see is the same factory part number traceable back to the original build specification.
A flat washer serves as a load-spreading interface between a fastener — bolt head or nut — and the surface it clamps against. By distributing clamping force over a wider area, it prevents the fastener from pulling through softer materials, protects mating surfaces from damage, and helps maintain consistent torque retention even under repeated vibration. On equipment like concrete mixers, plate compactors, and concrete pumps, where vibration and cyclical loading are constant, a worn, missing, or incorrectly sized washer can allow fasteners to work loose over time, leading to structural movement, accelerated wear on surrounding components, and potential mechanical failure.
