The Multiquip 933243 is a genuine OEM Flat Washer SAE 7/16 Grade 9 designed for JWN24HTCSL series ride-on power trowels. As a factory-sourced component, it meets the exact material and dimensional standards set for this machine, ensuring proper load distribution and secure fastener seating. This part is confirmed for JWN24HTCSL applications, making it a straightforward like-for-like swap when servicing or rebuilding affected assemblies. Sourcing 933243 direct from the OEM supply chain means you get the correct grade and zinc yellow coating specification without guesswork.
Key Features
- Grade 9 Hardness Rating — High-strength SAE Grade 9 construction provides superior tensile strength compared to standard hardware-grade washers, standing up to the high-stress fastener loads found in ride-on trowel assemblies.
- Zinc Yellow (YZ) Corrosion Protection — The zinc yellow chromate finish resists rust and surface corrosion, maintaining fastener clamp load integrity even after repeated exposure to concrete slurry and outdoor jobsite conditions.
- SAE 7/16 Bore Specification — Dimensioned to SAE standard for 7/16-inch fasteners, the washer seats flush and installs directly without any reworking of mating hardware or mounting surfaces.
- Confirmed OEM Fitment for JWN24HTCSL — Genuine Multiquip part 933243 is sourced directly through the OEM supply chain and verified for JWN24HTCSL ride-on power trowel applications.
- Proper Load Distribution — A correctly rated washer spreads clamping force evenly across the mating surface; using an undersized or incorrect-grade washer risks fastener loosening or surface damage during operation.
A flat washer serves as a load-distributing interface between a fastener head or nut and the surface it bears against. By spreading the clamping force over a wider area, it prevents the fastener from pulling through or damaging softer base materials and helps maintain consistent clamp load over time. When a washer is missing, worn, or substituted with an incorrect grade, fasteners can work loose under vibration — a particular concern on ride-on power trowels where the drivetrain and blade assemblies generate continuous cyclical loads during finishing operations.
