The Multiquip 42353 is a genuine OEM Hex Nut Serrated Flange M10-1.5 designed for Multiquip and Whiteman ride-on power trowel and power float models including the LD60, MD80, MD105, PRX, STX6H, HTX6H, HTXG6DF, STXDF, and LD6/LD6SL series. As a direct OEM part, 42353 is manufactured to the exact specification required by these machines, ensuring the correct thread pitch, flange geometry, and serration pattern every time. This fastener is stocked and sold by DHS Equipment as an authorized Multiquip replacement part. Confirm your model code against the fitment list before ordering to ensure compatibility.
Key Features
- OEM Thread and Flange Specification — M10-1.5 thread pitch and serrated flange profile match the original fastener exactly, maintaining proper clamp load across critical assemblies.
- Serrated Flange Locking Action — The integrated serrations bite into the mating surface during torquing, resisting loosening from vibration without requiring a separate lock washer.
- Broad Ride-On Trowel Fitment — Confirmed fit across LD60, MD80, MD105, PRX, STX6H, HTX6H, HTXG6DF, STXDF, and LD6/LD6SL ride-on trowel and power float models.
- Direct OEM Replacement — Sourced directly from Multiquip, this fastener drops into the same position as the original with no modification to surrounding hardware or mounting points.
- Structural Integrity on High-Vibration Equipment — Ride-on trowels generate sustained mechanical vibration during operation; using the correct OEM-spec fastener in fastener-critical locations helps maintain assembly integrity over the long service life of the machine.
A serrated flange hex nut combines a standard hex nut with a built-in washer flange that features radial serrations on its bearing surface. When the nut is tightened, those serrations grip the surface of the mating component, creating a mechanical lock that resists backing off under vibration — a common failure mode on equipment that runs with continuous oscillating or rotational motion. On ride-on power trowels, where blade assemblies, gearboxes, and drive components are subject to constant vibration and load cycling, maintaining proper fastener torque is essential to safe and consistent machine operation. A loose or incorrect fastener in these locations can lead to component misalignment, accelerated wear on adjacent parts, or structural failure of the assembly it secures.
