Key Features
- Genuine OEM Material Grade — Manufactured to the precise thickness and hardness specification required for load distribution in Multiquip equipment, unlike generic hardware-store equivalents.
- Drop-In Hardware Fitment — Sized at 5/8 inch to seat flush against the fastener and mating surface without shimming, trimming, or adjustment.
- Confirmed Compatibility — Verified for EM120SM Essick mixers and C30HDZ, C30HDGA, and C30HD Mayco concrete pumps.
- Consistent Clamping Surface — Distributes bolt load evenly across the joint, preventing fastener pull-through and surface deformation on critical assemblies.
- Direct OEM Source — Sourced from Multiquip's authorized parts network, so the part number, spec, and packaging match what the machine was built with.
A flat washer serves as a load-distribution interface between a fastener — such as a bolt head or nut — and the surface it bears against. By spreading clamping force over a wider area, the washer prevents the fastener from pulling into or damaging the material beneath it, which is especially important on assemblies subject to vibration, as found in concrete mixers and pump housings. When a washer is missing, undersized, or worn thin, the joint can loosen prematurely or the surrounding material can deform, leading to misalignment or fastener failure over time.
