The Multiquip 0478 is a genuine OEM HHCS 3/8-24X2.1/4" designed for B Series, JTO Series, and HDA Series power trowels. As a direct OEM replacement, this fastener is sourced to the same specifications as the original hardware installed at the factory, ensuring correct thread engagement and clamping load. Verified fitment covers B Series walk-behind trowels, JTO Series ride-on trowels, and HDA Series walk-behind trowels. When replacing worn or damaged hardware on your power trowel, using the correct OEM fastener matters — part number 0478 takes the guesswork out of the process.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the same thread pitch, grip length, and tensile grade as the original hardware, ensuring correct clamping force on critical trowel assemblies.
- Direct Drop-In Replacement — 3/8-24 fine-thread profile matches the existing threaded bores on compatible trowel models, allowing straightforward installation with standard tooling.
- Broad Trowel Family Fitment — Compatible with B Series walk-behind, JTO Series ride-on, and HDA Series walk-behind power trowels, covering a wide range of Multiquip and Whiteman trowel equipment.
- Structural Integrity Where It Counts — Power trowel assemblies rely on properly torqued fasteners to maintain blade pitch, guard alignment, and frame rigidity. The correct bolt prevents loosening under the continuous vibration loads generated during finishing work.
- Genuine OEM Part — Sold as a genuine Multiquip OEM component, part number 0478, so you can be confident the hardware meets the original design intent for your machine.
A hex head cap screw (HHCS) is a standard threaded fastener used throughout power trowel assemblies to secure components such as guards, blade spider arms, handles, and frame brackets. The 3/8-24 designation specifies the thread diameter and fine-thread pitch, which provides greater clamping strength and better resistance to loosening compared to coarse-thread equivalents — an important characteristic on equipment that operates under constant vibration. When a fastener in a critical location stretches, strips, or shears, it can allow components to shift or detach, directly affecting finishing quality and operator safety. Replacing damaged hardware with the correct OEM specification bolt restores the connection to its intended clamping capacity.
