The Wacker Neuson is a genuine OEM Jam Nut 1/2-13 designed for the CRT46KHN, CRT46KHO, and CRT46ASO ride-on concrete trowels. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct thread engagement every time. This Jam Nut 1/2-13 is the same part used during original assembly, so it installs cleanly against mating fasteners and components without the need for adjustment or rework. If your CRT46 series ride-on trowel needs a hardware replacement, this is the verified part to trust.
Key Features
- OEM-Grade Thread Integrity — Manufactured to precise 1/2-13 UNC thread specifications, this jam nut delivers the correct clamping profile and torque retention that fastener-critical trowel assemblies demand.
- Drop-In Hardware Replacement — Matches the original fastener dimensions exactly, threading directly onto existing 1/2-13 studs and bolts with no chasing or modification of mating hardware.
- Confirmed Fitment for CRT46 Ride-On Trowels — Verified for the CRT46KHN, CRT46KHO, and CRT46ASO models, covering both KH (Honda-powered) and AS (electric) variants of the CRT46 series.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this jam nut carries the same part number — 5000113771 — referenced in the official parts documentation for these machines.
- Prevents Fastener Loosening Under Vibration — A jam nut locks an adjacent nut or threaded component in place; using the correct OEM hardware ensures it holds under the continuous vibration loads generated during concrete finishing operations.
A jam nut is a thin secondary nut threaded onto a bolt or stud and tightened against a primary nut to prevent it from backing off under load or vibration. On ride-on concrete trowels like the CRT46 series, fastener security is critical — the machine operates under sustained rotational forces across the trowel arm and rotor assemblies, and any hardware that loosens can affect blade pitch, operator control, or structural integrity. Replacing a worn, stripped, or missing jam nut with the correct OEM part restores proper fastener lock and helps maintain the mechanical integrity of the assembly it secures.
