The Multiquip 6904 is a genuine OEM Hex Finish Nut 1/4-28 Zinc Plated designed for HTX44, STX55, STXD6i, HTXD6i, and WRS5200 series ride-on power trowels and roller screeds. As a direct Multiquip OEM component, part 6904 is produced to the same specifications as the hardware originally installed on your machine, ensuring a correct and consistent fit every time. This nut is confirmed compatible across a broad range of Whiteman ride-on power trowel models including the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, STXD6i, and HTXD6i, as well as WRS5200 and WRSPUDF roller screed units. Sourcing the correct OEM fastener keeps your equipment assembled to spec and prevents the loosening or fastener failure that can result from using mismatched hardware.
Key Features
- Genuine OEM Zinc-Plated Hardware — Produced to Multiquip's original specification with a zinc plating that provides corrosion resistance in demanding outdoor and jobsite conditions.
- Correct 1/4-28 Fine Thread Profile — The fine thread pitch matches the original tapped fastener points on your machine, ensuring full thread engagement and secure clamping without cross-threading risk.
- Broad Ride-On Trowel and Screed Compatibility — Fits HTX44, STX55, STXD6i, HTXD6i, and WRS5200 series equipment, covering Kubota, Yanmar, and diesel-powered Whiteman ride-on power trowels and roller screeds.
- Direct Drop-In Replacement — Matches the original fastener dimensions exactly, so installation requires only standard hand tools with no reworking of mounting points.
- Prevents Structural Loosening — A worn or incorrect nut on a ride-on trowel or screed assembly can allow components to shift under vibration, leading to misalignment and accelerated wear on surrounding hardware.
A hex finish nut is a standard internal-thread fastener used throughout machine assemblies to secure bolts, studs, and threaded components in place. On ride-on power trowels and roller screeds, these nuts are used across frames, guard assemblies, drive components, and ancillary mounting points where consistent clamping force is critical. The zinc plating on part 6904 provides a protective barrier against rust and surface corrosion, extending the service life of the fastener even when exposed to moisture, concrete slurry, and the elements. When a nut becomes stripped, corroded, or lost during service, replacing it with the correct OEM part ensures the joint returns to its original clamping specification rather than introducing an undersized or thread-mismatched substitute.
