The Wacker Neuson is a genuine OEM Lock Nut designed for the CT24-4A and CT24-230E series walk-behind concrete power trowels. As a direct factory replacement, this Lock Nut is manufactured to the same specifications as the original part installed at the time of production. It is compatible across both standard and EU-configured CT24 trowel variants, including the 610mm/24-inch walk-behind models. Confirm your model number before ordering to ensure proper fitment.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original thread profile and hardness grade, ensuring correct clamping force and resistance to backing off under vibration.
- Drop-In Replacement — Matches the original fastener geometry exactly, threading directly into the existing mounting position without modification to adjacent components.
- Broad CT24 Series Coverage — Fits the CT24-4A and CT24-230E, including standard and EU-configured 24-inch walk-behind concrete trowel variants.
- Vibration Retention — Lock nut design resists loosening under the continuous operational vibration generated by a rotating concrete trowel, maintaining fastener integrity throughout extended finishing sessions.
- Fastener Integrity Matters — A loose or failed lock nut on rotating trowel assemblies can allow critical components to shift during operation, making timely replacement essential for safe machine use.
A lock nut is a fastener engineered to resist unintentional loosening caused by vibration, torque, or dynamic loads. On a walk-behind concrete power trowel like the CT24 series, rotating assemblies generate continuous vibration that can work standard fasteners loose over time. The lock nut's locking mechanism — whether through a nylon insert, prevailing torque design, or deformed thread profile — maintains clamping force even under these demanding conditions. When a lock nut wears out, strips, or goes missing, the components it secures can shift or separate, leading to misalignment, accelerated wear on surrounding parts, or an unsafe operating condition.
