The Multiquip 25307 is a genuine OEM HHC M6-1.0 x 50mm Patch Screw designed for Whiteman ride-on power trowel models HTX6H, HTXG6DF, STX6H, and STXDF. As a factory-sourced fastener, it meets the exact thread pitch, head geometry, and patch-locking specifications called for in the original equipment design. Sourcing the correct OEM screw ensures proper clamping force and thread engagement, keeping critical assemblies secured through demanding finishing operations. DHS Equipment supplies this part direct from Multiquip, so you can trust you are receiving the right component for your machine.
Key Features
- Precision Thread Specification: — M6-1.0 thread pitch matches the tapped holes on HTX and STX trowel assemblies exactly, ensuring full thread engagement without binding or cross-threading.
- Patch-Locking Design: — The nylon patch on the screw shank resists vibration-induced loosening, which is critical on ride-on trowels subject to continuous rotational vibration during concrete finishing.
- Genuine OEM Sourcing: — Manufactured to Multiquip's original fastener specification, so head dimensions, tensile grade, and patch compound are identical to what left the factory.
- Broad HTX and STX Series Fitment: — Confirmed for HTX6H, HTXG6DF, STX6H, and STXDF hydrostatic ride-on trowels, covering both standard and dual-fuel configurations.
- Maintains Structural Integrity: — A worn or missing patch screw allows fastened components to work loose under load, potentially causing misalignment of trowel arms, guards, or drive components during operation.
A hex head cap screw with a patch lock is a hardened fastener used to clamp two or more components together at a fixed torque, while the pre-applied nylon patch on its threads creates friction that prevents the screw from backing out under vibration. On a ride-on power trowel, these screws appear throughout the frame, gearbox covers, and blade arm assemblies, where constant rotational forces would otherwise work standard fasteners loose over time. When a patch screw fails or is replaced with an incorrect substitute, the assembly it secures can shift, create play, or come apart entirely, leading to uneven blade pitch, accelerated component wear, or an unsafe operating condition.
