Multiquip 23802 Hex Flange Nut M8-1.25 Serrated

The Multiquip 23802 is a genuine OEM Hex Flange Nut M8-1.25 Serrated designed for a wide range of Multiquip and Whiteman ride-on power trowels, including MD105, MD80, STX, HTX, LD60, LD6, PRX, and STXDF series machines. As a factory-sourced fastener, part 23802 meets the exact torque retention and dimensional requirements called out in the original equipment build. Verified fitment across multiple ride-on trowel platforms makes this the correct choice when replacing hardware during scheduled maintenance or field repairs. Order directly from DHS Equipment for genuine Multiquip parts backed by authorized distribution.

Key Features

• Serrated Flange Locking Action — The built-in serrated flange bites into the mating surface to resist vibration-induced loosening, critical on trowel powertrains that run under sustained oscillating loads.
• Genuine OEM Fastener Specification — Manufactured to the exact M8-1.25 thread pitch, flange diameter, and hardness grade specified by Multiquip, ensuring consistent clamp load every time.
• Broad Ride-On Trowel Fitment — Confirmed fit across MD105, MD80, STX, HTX, LD60, LD6, LD6SL, PRX, STXDF, and HHXDF4-DF5 series ride-on trowels — one part number covering multiple platforms.
• Drop-In Hardware Replacement — Matches the original thread engagement depth and flange geometry, so no reworking of mounting holes or use of additional locking hardware is needed.
• Protects Structural Integrity of Fastened Joints — A worn or missing flange nut on a trowel can allow critical guards, covers, or drive components to shift under load; replacing with the correct OEM nut restores joint integrity immediately.

A serrated hex flange nut combines a standard hex nut with an integrated washer-like flange that features teeth or serrations on its bearing face. When torqued down, those serrations embed into the clamping surface and create a mechanical lock that resists loosening from vibration and dynamic loads. On ride-on power trowels — machines that transmit constant rotational and oscillating forces through their frames and blade assemblies — maintaining correct fastener clamp load is essential to keeping structural and drivetrain joints secure. A nut that backs off even slightly can allow movement that accelerates wear on adjacent components or creates unsafe operating conditions.
