Multiquip 42325 HHC M6-1.0 X 20 Cap Washer Screw

The Multiquip 42325 HHC M6-1.0 X 20 Cap Washer Screw is a genuine OEM fastener designed for Multiquip and Whiteman ride-on power trowels and power floats, including the LD60, MD80, MD105, STX, HTX, PRX, HTXG6DF, STXDF, HTX6H, STX6H, LD6, and HHXDF4-DF5 series. As an OEM part, it is manufactured to the exact specification of the original hardware used on these machines, ensuring consistent fit and proper torque retention. Sourced directly through Multiquip's authorized parts network, the 42325 is the correct replacement when original fasteners are worn, stripped, or lost during service. Confirm your model against the fitment list above before ordering to ensure compatibility.

Key Features

• Genuine OEM Fastener Specification — Manufactured to the exact M6-1.0 x 20 thread pitch and cap washer head geometry specified for Multiquip ride-on trowel assemblies, ensuring correct clamping force and seating.
• Direct Hardware Replacement — Installs in place of the original screw with no thread chasing or rework required on properly maintained threaded bores.
• Broad Ride-On Trowel Fitment — Compatible with LD60, MD80, MD105, STX, HTX, HTX6H, STX6H, HTXG6DF, STXDF, PRX, LD6, LD6SL, and HHXDF4-DF5 series machines.
• Structural Integrity at Critical Joints — Using the correct OEM-spec fastener maintains proper clamp load at trowel assembly connection points, preventing loosening under the vibration loads generated during finishing operations.
• Fastener Safety Compliance — On rotating trowel assemblies, undersized or incorrect fasteners can back out under operational load; using the specified 42325 ensures the joint meets the original design's retention requirements.

The HHC M6-1.0 x 20 Cap Washer Screw is a hex head cap screw with an integrated washer bearing surface, used to secure components within the trowel's mechanical assembly. The cap washer head distributes clamping load over a wider surface area than a standard hex head, which helps prevent fastener pull-through or surface damage on the mating component. When this fastener is missing, stripped, or replaced with an incorrect substitute, joint integrity is compromised, which can lead to component movement, accelerated wear at the mating surfaces, and potential fastener ejection during machine operation.
