The Multiquip 12402 is a genuine OEM HHC Screw 1/2-13 x 2 1/2 designed for Whiteman ride-on power trowel models including HHXD5, HHXG5, STXD6i, HTXD6i, HHXD5-ES, HHXDF4-DF5, LD6, LD6SL, and LD60. As a factory-sourced fastener, part 12402 is manufactured to the exact thread pitch, grade, and dimensional spec required for a secure, lasting installation. Sourcing the correct OEM hardware ensures the fastened joint performs as designed under the operational loads these machines generate. DHS Equipment stocks this part to get your trowel back to work without compromise.
Key Features
- Correct Thread Specification — 1/2-13 UNC thread pitch and 2 1/2-inch length match the original fastener exactly, ensuring full thread engagement in the mating bore.
- Genuine OEM Fastener — Sourced directly from Multiquip, this screw is made to the same material grade and hardness spec as the original hardware used on the production line.
- Broad Trowel Compatibility — Confirmed fitment across HHXD5, HHXG5, STXD6i, HTXD6i, HHXD5-ES, HHXDF4-DF5, LD6, LD6SL, and LD60 ride-on power trowel models.
- Structural Integrity Under Load — Ride-on trowels generate significant vibration and dynamic stress; an undersized or incorrect-grade fastener can back out or shear, taking other components with it.
- Drop-In Replacement — Hex head cap screw profile installs with standard tooling — no drilling, re-tapping, or modification to the machine needed.
A hex head cap screw is a structural fastener used throughout heavy equipment assemblies to clamp, secure, and align mating components under load. On ride-on power trowels, fasteners like the 12402 are critical at high-stress attachment points — including frame assemblies, guard brackets, and drive system housings — where vibration and operational torque are constant. Using a fastener with the correct thread form, grip length, and material grade preserves clamping force over time; an incorrect substitute can loosen, fatigue, or fail, leading to component movement that accelerates wear across the entire assembly.
