Wacker Neuson 5000087941 Lock Nut Stover 1/4-20

The Wacker Neuson is a genuine OEM Lock Nut Stover 1/4-20 designed for the CRT46 and CRT36 series ride-on concrete trowels. As a direct OEM part, is manufactured to the exact specifications required by these machines, ensuring a correct, secure installation every time. This fastener is compatible with the CRT46KHN, CRT46KHO, CRT46ASO, CRT36ASO, and CRT36ASN models, making it a straightforward replacement for technicians servicing this trowel family.

Key Features

• Genuine OEM Fastener Integrity — Stover-style prevailing torque design provides consistent locking force without relying on adhesives or separate locking inserts, maintaining holding strength through vibration and repeated trowel cycles.
• Correct Thread Specification — 1/4-20 UNC thread form matches the exact threaded hardware used on CRT46 and CRT36 assemblies, threading directly onto existing fastener points with no rework needed.
• Broad CRT Family Coverage — Fits the CRT46KHN, CRT46KHO, CRT46ASO, CRT36ASO, and CRT36ASN ride-on trowel models, covering both overlapping and standard rotor configurations.
• Vibration Resistance — The Stover one-piece all-metal locking geometry resists loosening under the continuous vibration and operational loads generated during concrete finishing passes.
• Safety-Critical Fastener — On ride-on concrete trowels, loose or failed fasteners in rotor and frame assemblies can create hazardous operating conditions; replacing worn hardware with the correct OEM nut restores structural integrity.

A Stover lock nut is a prevailing torque fastener that uses a deliberately distorted top section to create mechanical resistance against loosening — no secondary locking element is required. On ride-on concrete trowels like the CRT46 and CRT36 series, fasteners are exposed to constant vibration from the rotating trowel arms and engine, which can gradually work standard nuts loose over time. Using the correct 1/4-20 Stover lock nut in place of a worn or missing fastener restores the clamping load the assembly was engineered to maintain, preventing component shift, misalignment, or structural failure during operation.
