Multiquip 16083 Hex Nut M12-1.75 No Plate

The Multiquip 16083 Hex Nut M12-1.75 No Plate is a genuine OEM fastener designed for MD, STX, HTX, LD, PRX, and HHX series ride-on power trowels. As a factory-original component, 16083 meets the exact thread specification and material grade required by Multiquip for proper torque retention on these machines. This nut is confirmed to fit a wide range of hydrostatic and hybrid ride-on trowel models including MD105, MD80, STX6H, STXDF, STXD6i, HTX6H, HTX44Y5, HTX44Y4, HTX44K5, HTX44K4, HTXD6i, HTXG6DF, LD60, LD6, PRX, STX55Y6, STX55J6, HHXDF4-DF5, HHXD5-ES, HHXG5, and HHXD5. Keeping the correct fastener hardware on hand helps ensure your trowel stays in service through demanding concrete finishing work.

Key Features

• M12-1.75 Thread Specification — Matches the exact thread pitch required for correct engagement and clamping load on ride-on trowel assemblies.
• Genuine OEM Grade — Factory-original Multiquip hardware ensures the correct material hardness and dimensional tolerancing for torque-critical fastener positions.
• Unplated Finish — No Plate designation indicates an uncoated finish, matching the OEM specification wherever bare hardware is required to avoid dimensional interference.
• Broad Trowel Family Coverage — Fits MD, STX, HTX, LD, PRX, and HHX series hydrostatic and hybrid ride-on trowels, making it a versatile stocking part for fleets running multiple Multiquip trowel models.
• Prevents Fastener-Related Failures — A correct-spec nut maintains proper clamp force across trowel components; an incorrect or worn fastener can lead to loosening under vibration and unplanned disassembly.

A hex nut is a standard internally threaded fastener used to secure bolted connections throughout a machine's frame, drive components, and attached assemblies. On ride-on power trowels, fasteners are subjected to continuous vibration from rotating blade assemblies and engine operation, making thread specification and material grade critical to joint integrity. Using the wrong thread pitch or a worn nut can result in improper clamping, which may allow components to shift or come loose during operation.
