The Multiquip 9161 Hex Flanged Nut M12-1.75 GR8 is a genuine OEM fastener designed for Whiteman ride-on power trowel models HHXD5, HHXG5, HHXD5-ES, and HHXDF4-DF5, as well as PRX hybrid ride-on power float equipment. As a direct OEM replacement, this M12-1.75 Grade 8 hex flanged nut delivers the clamping strength and dimensional accuracy required for safe, stable assembly on professional concrete finishing machines. Sourced directly through Multiquip's authorized parts network, part 9161 is the correct specification for these applications — no guesswork on thread pitch or grade. DHS Equipment stocks genuine Multiquip OEM parts so you can get the right component and get your machine back to work.
Key Features
- Grade 8 Clamping Strength — The GR8 rating delivers high tensile strength and torque resistance, critical for fastener joints on rotating and load-bearing assemblies in ride-on trowel applications.
- M12-1.75 Thread Specification — Correct metric thread pitch ensures full thread engagement and a secure, properly tensioned connection with mating components on the machine.
- Integrated Flange Bearing Surface — The flanged design distributes clamping load across a wider surface area, reducing stress concentration and the risk of fastener loosening under vibration.
- Genuine OEM Part — Manufactured to Multiquip's original specifications, ensuring dimensional accuracy and material grade that match what was installed at the factory.
- Confirmed Fitment — Verified for HHXD5, HHXG5, HHXD5-ES, HHXDF4-DF5, and PRX series ride-on trowels and power floats under part number 9161.
A hex flanged nut combines a standard hex nut with an integrated flange that acts as a built-in washer, spreading the load over a larger contact area than a standard nut alone. On ride-on power trowels and power floats, fasteners are subjected to continuous vibration from rotating blade assemblies and engine operation, which can cause conventional nuts to back out over time. The flanged design and Grade 8 hardness of the Multiquip 9161 work together to maintain joint integrity under these demanding conditions — a worn, incorrect, or under-grade replacement nut risks fastener failure, component loosening, and potential damage to the machine or surrounding assemblies.
