The Wacker Neuson is a genuine OEM Lock Nut 3/4-10 Plated designed for a wide range of Wacker Neuson light towers and ride-on concrete trowels. As a direct factory replacement, this plated lock nut meets the exact specifications of the original hardware used on LT4K, LTP4K, LT4Z, LTP4Z, LTW4Z, LTWP4Z, LTW4K, LTWP4K, LTW6Z, LT4SK, LTP4SK, LT4SZ, LTP4SZ, and CRT46 series machines. Sourced directly from Wacker Neuson, part number ensures you are installing the correct fastener with the correct thread specification — no guesswork required. This is a straightforward but critical hardware component that keeps structural and mechanical connections secure across multiple machine platforms.
Key Features
- Genuine OEM Thread Integrity — Manufactured to the exact 3/4-10 UNC thread specification, ensuring full thread engagement and correct torque retention without stripping or cross-threading risk.
- Plated Finish for Corrosion Resistance — The zinc plating on this lock nut protects against rust and surface corrosion, particularly important on equipment exposed to outdoor jobsite conditions.
- Locking Design Prevents Fastener Loosening — The lock nut configuration resists vibration-induced loosening, maintaining clamping force on assemblies subject to continuous mechanical movement or engine vibration.
- Broad Fitment Across LT and CRT Series — Confirmed fit across LT4K, LTW, LTP, LT4S, and CRT46 series machines, covering multiple light tower and ride-on trowel configurations from Wacker Neuson.
- Direct Factory Replacement — Part number 5000089782 matches the OEM hardware specification exactly, dropping into place on any compatible Wacker Neuson machine without modification to mating components.
A lock nut is a fastener engineered to resist loosening under vibration and dynamic loads — conditions that standard nuts cannot reliably handle over time. On light towers and ride-on concrete trowels, fasteners are subjected to engine vibration, transport movement, and continuous mechanical stress, all of which can gradually back a conventional nut off its stud or bolt. When a lock nut fails or goes missing, the connected assembly can shift, come loose, or cause accelerated wear to surrounding components. Using the correct OEM-specified lock nut, such as Wacker Neuson 5000089782, ensures the fastener performs as the machine was engineered to require.
