The Multiquip 1404 is a genuine OEM HHC Bolt 5/16-18 x 3-1/4 #5 designed for STX55, HTX44, STXD6i, HTXD6i, and STX55Y6 ride-on power trowels, UWK1, UWK2, UWK1A, and UWK2A wheel kits, and the G55H vibrator. As a factory-original fastener, it meets the exact thread specification, head geometry, and grade requirement called out in the Multiquip bill of materials for these machines. Sourced directly through authorized channels, part number 1404 is a direct drop-in replacement that installs without modification. Keep a supply on hand — fasteners at this size and grade are a frequent service item across the trowel and wheel kit assemblies where this bolt is used.
Key Features
- Correct Grade and Thread Specification — Manufactured to the exact 5/16-18 thread pitch and #5 grade required by the Multiquip bill of materials, ensuring proper clamping force and joint integrity.
- Genuine OEM Hardware — Factory-original part 1404 sourced through authorized Multiquip supply channels, identical to what shipped with the machine at the time of manufacture.
- Broad Fitment Across Trowel and Wheel Kit Families — Compatible with STX55J6, STX55Y6, HTX44Y4, HTX44Y5, STXD6i, HTXD6i ride-on trowels, UWK1, UWK2, UWK1A, UWK2A wheel kits, and the G55H vibrator.
- Drop-In Installation — Hex head configuration matches the original fastener geometry, fitting standard tooling already on the job.
- Structural Reliability in High-Vibration Environments — Ride-on trowels and concrete vibrators generate continuous vibration during operation; using the specified grade fastener helps maintain joint security and prevents loosening over time.
A hex head cap bolt like the Multiquip 1404 serves as a primary structural fastener, clamping two or more components together and maintaining alignment under load. In ride-on trowel assemblies and wheel kit configurations, fasteners at this location are subjected to sustained vibration and rotational forces during concrete finishing operations. Using a bolt of the correct thread engagement, head size, and grade is critical — an undersized or incorrect-grade fastener can back out, strip, or fail under load, leading to component misalignment or unexpected disassembly. Replacing worn or damaged fasteners with the correct OEM specification part restores the joint to its original clamping integrity.
