The Multiquip 9165 is a genuine OEM Screw HFS 1/4-28 x 3/4 Patchcase Hard designed for Whiteman and International ride-on power trowels including the HHN31V, HHN34TVD, HHXD5, HHXD5-ES, HHXG5, HHNG5, HHXDF4-DF5, and EHHNK5 series. As a direct OEM replacement, this fastener is manufactured to the same specification as the original hardware — ensuring correct thread engagement, head geometry, and patch-locking performance in the exact assembly location it was designed for. Sourced directly from Multiquip, part 9165 delivers the fit and integrity you expect when returning a machine to service. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Thread and Patch Specification — Manufactured to the exact 1/4-28 thread pitch and patch-lock hardness grade specified by Multiquip for this fastener position, maintaining correct clamp load in the assembly.
- Direct Bolt-In Replacement — Matches the original hole pattern and head drive type of the factory hardware, allowing straightforward installation without rework or thread chasing.
- Broad Trowel Family Coverage — Compatible with HHN31V, HHN34TVD, HHXD5, HHXD5-ES, HHXG5, HHNG5, HHXDF4-DF5, and EHHNK5 ride-on power trowels.
- Patchcase Hard Locking Feature — The patch-locking compound on the thread resists loosening under the vibration loads typical of ride-on trowel operation, maintaining joint integrity over extended run cycles.
- Correct Fastener for Safety-Critical Assemblies — Using the specified OEM fastener in patch-locked positions ensures the assembly retains its designed clamping force, which is important wherever trowel drive or guard components are secured.
A patchcase hard screw is a machine fastener with a pre-applied dry-film patch on a portion of its threads that acts as a self-locking element when the screw is driven into a tapped hole. The patch material compresses and deforms against the mating threads, creating resistance to rotation that prevents the fastener from backing out under vibration. On ride-on power trowels — where blade rotation, engine vibration, and operator movement generate continuous mechanical stress — this locking characteristic is essential for keeping structural and drive-system assemblies properly secured. A worn, stripped, or incorrect substitute fastener in this position risks joint loosening, component misalignment, and potential damage to surrounding hardware.
