The Multiquip 90380MB2000 is a genuine OEM Special Screw 6x8 Honda GX690 designed for JWN24 series non-overlapping blade ride-on power trowels. As a direct OEM replacement, this screw is manufactured to the exact dimensions and thread specification required by the Honda GX690 engine fitted to JWN24HTCSL and JWN24HSCSL models. Sourcing the correct fastener matters — an incorrect screw can compromise component seating, lead to oil or cover leaks, and cause secondary engine damage. Trust the genuine Multiquip 90380MB2000 to restore your machine to proper operating condition.
Key Features
- Genuine OEM Fastener Specification — Machined to the precise 6x8 thread profile and hardness grade required by the Honda GX690 engine, ensuring correct torque retention without stripping or backing out.
- Drop-In Engine Replacement — Matches the original mounting point geometry on the GX690, seating flush without rework or thread chasing.
- Confirmed Fitment for JWN24 Trowels — Verified for JWN24HTCSL and JWN24HSCSL non-overlapping blade ride-on power trowel models.
- Protects Engine Integrity — A correctly torqued OEM-spec screw maintains proper cover and component clamping force, preventing oil weepage and vibration-induced loosening during trowel operation.
- Direct Multiquip OEM Part — Sourced directly through the Multiquip OEM supply chain, so the part number, dimensions, and material grade match what left the factory.
A special screw of this type serves as a precision fastener within the Honda GX690 engine assembly, securing covers, brackets, or internal components that require a non-standard thread form or shoulder geometry beyond what a common metric screw provides. Because the GX690 operates under sustained vibration loads typical of ride-on trowel work, the fastener must maintain clamping force across extended run cycles — a mismatched or worn screw can back out over time, allowing components to shift or leak. Replacing it with the correct Multiquip 90380MB2000 restores the engineered clamping integrity the GX690 depends on.
