The Multiquip 42443 Hex Lock Nut M12-1.75 Deformed is a genuine OEM fastener designed for the HTXG6DF ride-on power trowel. As a direct Multiquip OEM component, 42443 is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct thread engagement and seating fit on your machine. This nut is cross-referenced to the HTXG6DF and is the recommended replacement when servicing fastener points on that model.
Key Features
- Deformed-Thread Locking Profile: — The deformed M12-1.75 thread profile creates mechanical resistance against loosening under vibration — critical on a ride-on trowel that generates continuous rotational forces during operation.
- Genuine OEM Hardware Grade: — Sourced directly from Multiquip, this nut meets the same material and thread-tolerance standards as the original fastener, ensuring consistent clamp load and thread integrity.
- Direct Fit for HTXG6DF Trowels: — Part 42443 is verified for the Multiquip HTXG6DF ride-on power trowel, threading directly onto existing M12-1.75 stud and bolt points with no modification to mating hardware.
- Prevents Fastener Backing Out: — A worn or missing lock nut on a ride-on trowel can allow critical assemblies to work loose during use; replacing with the correct deformed-thread nut restores the intended retention force.
- Exact Part Number Reference: — Order with confidence using Multiquip part number 42443 to confirm you are receiving the correct nut specification for your machine.
A hex lock nut uses a deformed or distorted thread section near its top to create interference with the mating bolt threads, resisting self-loosening caused by vibration and dynamic loads. On ride-on power trowels like the HTXG6DF, where rotating blade assemblies and drive components generate sustained vibration, maintaining correct fastener torque and retention is essential to safe and stable operation. When a lock nut loses its locking effectiveness — through wear, over-torquing, or repeated reuse — it should be replaced promptly to prevent component movement or detachment during use.
