The Multiquip 3109 Flat Washer 3/8 is a genuine OEM replacement designed for MQ Mixer models including the MC64P/S, MC94P/S, MC64SK/MC64PK, and MC94SK/MC94PK series. As a direct OEM component sourced through Multiquip's authorized parts program, part 3109 is manufactured to the exact dimensions required for correct fastener load distribution on these concrete mixers. Keeping the correct washer in place ensures fastened connections stay torqued and secure through the continuous vibration and rotation demands of mixing operation. DHS Equipment stocks this genuine OEM part to help you get your mixer back to work with confidence.
Key Features
- OEM-Matched Dimensions — Manufactured to the exact 3/8" specification required for correct load-bearing performance on Multiquip concrete mixer fastener assemblies.
- Direct-Fit Hardware — Replaces part 3109 on a one-for-one basis, seating correctly against mating fasteners and surfaces without modification.
- Broad MQ Mixer Compatibility — Confirmed fitment across MC64P/S, MC94P/S, MC64SK/MC64PK, and MC94SK/MC94PK Multiquip concrete mixer models.
- Sustained Clamping Force — A correctly sized flat washer distributes fastener load evenly, preventing bolt pull-through or surface deformation under the repetitive stress of mixing cycles.
- Genuine OEM Quality — Supplied as an authentic Multiquip OEM part, meeting the same material and dimensional standards as the original hardware installed at the factory.
A flat washer serves as a load-distribution interface between a fastener — such as a bolt or nut — and the surface it clamps against. By spreading clamping force across a wider area, the washer prevents the fastener head from pulling into or damaging the mating surface, and helps maintain consistent clamp load over time. On concrete mixers like the MC64 and MC94 series, where vibration and rotational forces are constant during operation, a worn, missing, or incorrect washer can allow fasteners to loosen progressively, leading to component movement, accelerated wear, or structural failure at the connection point.
