Wacker Neuson 5000117632 Lock Nut 1/2-20 Hex with Nylon

The Wacker Neuson Lock Nut 1/2-20 Hex with Nylon is a genuine OEM fastener designed for the CRT series ride-on concrete trowels, spanning the CRT36, CRT48, and CRT60 model families. As a direct OEM component sourced from Wacker Neuson, part is manufactured to the exact specifications required for correct installation and long-term holding strength in these machines. This lock nut fits an extensive range of CRT models including the CRT36-24A, CRT36-25, CRT36-26A, CRT48-31V, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, CRT48-57K, CRT60-66K, and CRT60-74L series, among others. Genuine OEM designation means this part matches the original hardware installed at the factory, giving you confidence in fit and thread engagement from the first turn.

Key Features

• Nylon Insert Locking: — The nylon collar deforms around the thread on installation, resisting vibration-induced loosening during trowel operation.
• Genuine OEM Fastener: — Sourced directly from Wacker Neuson, this 1/2-20 hex lock nut meets the exact thread pitch, material grade, and dimensional tolerances specified for the CRT series.
• Broad CRT Series Coverage: — Fits CRT36, CRT48, and CRT60 ride-on trowel families across a wide range of model variants, including standard, high-speed, dual-fuel, and EU-spec configurations.
• Maintains Clamping Force Under Load: — Correct torque retention keeps critical assemblies secure during the high-RPM, vibration-intensive work cycles that ride-on trowels endure on concrete finishing jobs.
• Drop-In Hardware Replacement: — Standard 1/2-20 hex configuration installs with common hand tools, requiring no special adapters or hardware modifications.

A lock nut with a nylon insert is a prevailing-torque fastener designed to stay tight under vibration and dynamic loading. The nylon collar grips the bolt threads after installation, preventing the nut from backing off even when the machine is running at high speed or encountering uneven resistance across the trowel pan. On ride-on concrete trowels like the CRT series, loose fasteners in the rotor, gearbox, or frame assemblies can lead to accelerated wear on adjacent components or loss of control at the troweling head. Replacing a worn or missing lock nut with the correct OEM part restores the clamping integrity the assembly was designed around.
