The Multiquip 21584 is a genuine OEM HHC Screw M10-1.5X35MM Grade 10.9 designed for HTX6H, STX6H, HTXD6i, and STXD6i hydrostatic ride-on power trowels. As a factory-sourced fastener, part 21584 meets the exact torque and tensile specifications required for critical structural and drivetrain connections on these machines. Sourced directly through Multiquip's authorized parts network, this screw ensures a correct fit with no guesswork at installation. If you're servicing or reassembling a Multiquip ride-on trowel, using the specified OEM hardware is the straightforward choice.
Key Features
- Grade 10.9 Tensile Strength — High-strength metric fastener rated to Grade 10.9, providing the clamping force and shear resistance demanded by heavy-duty trowel assemblies.
- Genuine OEM Sourced — Factory-spec part direct from Multiquip, confirming correct thread pitch (M10-1.5) and length (35MM) for a true drop-in installation.
- Confirmed Fitment — Verified for HTX6H, STX6H, HTXD6i, and STXD6i hydrostatic ride-on power trowels.
- Correct Hardware Prevents Assembly Failures — Using an undersized or lower-grade substitute risks fastener stretch, loosening under vibration, or premature failure during troweling operations.
- Hex Head Cap Design — HHC profile allows proper torque application with standard tooling, ensuring consistent clamp load across mating surfaces.
A hex head cap screw is a precision fastener used to join and secure structural or mechanical components within the machine. In high-vibration equipment like ride-on power trowels, fastener grade matters — a Grade 10.9 screw is engineered to resist the dynamic loads and vibration cycles generated during concrete finishing without stretching or backing out. When fasteners wear, corrode, or are replaced with lower-grade hardware, joint integrity can be compromised, leading to component movement, accelerated wear on mating parts, or mechanical failure during operation.
