The Multiquip 22131 is a genuine OEM Carriage Bolt 10-32 x 3/4 Zinc designed for Whiteman ride-on power trowel models including the STXD6i, HTXD6i, JWN24HTCSL, and HHNG5. As a direct OEM part, 22131 meets the exact material and dimensional specifications Multiquip requires for these machines. Zinc plating provides corrosion resistance suited to the demanding conditions of concrete finishing work.

Key Features
- Genuine OEM Hardware Grade — Zinc-plated 10-32 x 3/4 carriage bolt manufactured to Multiquip's exact thread pitch and shank dimensions, ensuring consistent clamping load across fastened assemblies.
- Corrosion-Resistant Zinc Finish — Zinc coating protects against surface oxidation during exposure to moisture, concrete slurry, and outdoor storage conditions common on finishing jobsites.
- Direct Drop-In Replacement — Installs without modification into the existing bolt positions on compatible trowel assemblies, with the domed carriage head seating flush against mating surfaces.
- Confirmed Fitment for Whiteman Ride-On Trowels — Verified for STXD6i, HTXD6i, JWN24HTCSL, and HHNG5 series machines; use part number 22131 when ordering to confirm the correct specification.
- Structural Integrity Under Vibration — Carriage bolt geometry resists rotation in the mounting hole during machine operation, maintaining fastener tension even under the sustained vibration of ride-on trowel use.
A carriage bolt is a fastener with a smooth, domed head and a square shank section beneath it that locks into a matching hole to prevent the bolt from turning as the nut is tightened. In ride-on power trowel assemblies, carriage bolts are used to secure guards, panels, and structural components where a flush, snag-free head profile is required. When a carriage bolt loosens, backs out, or corrodes, the components it joins can shift or separate, compromising the integrity of the assembly and potentially creating a safety hazard. Replacing worn or missing hardware with the correct OEM specification fastener restores the designed clamping force and keeps the machine operating as intended.
