The Multiquip 42351 Screw HFS ZP M12-1.75 x 40 Class 8.8 is a genuine OEM fastener designed for Whiteman ride-on power trowels including the HTXG6DF, LD60, and LD6/LD6SL series. Sourced directly from Multiquip, part 42351 matches the original thread pitch, shank length, and strength grade specified for these machines. Class 8.8 construction delivers the tensile strength required for structural and mechanical fastening points on ride-on trowel assemblies. Verify your model against the fitment list to confirm compatibility before ordering.
Key Features
- Class 8.8 Tensile Strength — Medium-carbon steel fastener rated to Class 8.8, providing the clamping force required for load-bearing joints on ride-on power trowels.
- Zinc-Plated Finish — ZP coating guards against corrosion from moisture and concrete slurry exposure common in finishing work environments.
- Exact OEM Thread Specification — M12-1.75 thread pitch and 40 mm shank length match the original Multiquip engineering specification, threading directly into existing bosses without rework.
- Genuine Multiquip OEM Part — Pulled from the official Multiquip parts catalog as part number 42351, ensuring traceability and correct fitment for covered models.
- Confirmed Fitment — Fits HTXG6DF, LD60, and LD6/LD6SL Whiteman hydrostatic ride-on power trowels.
- Structural Integrity at the Fastener Level — Using the correct grade and size fastener prevents joint loosening, blade assembly misalignment, and premature wear on mating components.
A hex flange screw such as the Multiquip 42351 serves as a structural fastener throughout the trowel's mechanical and drive assemblies, using its integrated flange to distribute clamping load across a wider bearing surface without requiring a separate washer. The Class 8.8 grade rating indicates the screw is engineered to withstand significant tensile and shear stress, making it suitable for joints that experience vibration and cyclic loading during troweling operations. Using an incorrect grade or thread pitch in these positions can lead to fastener fatigue, joint movement, and potential damage to surrounding components.
