The Wacker Neuson Screw M8 X 10, Shoulder is a genuine OEM fastener designed for CRT36 and CRT48 series ride-on concrete trowels. As a direct Wacker Neuson OEM component, it is manufactured to the exact dimensional and material specifications required for proper assembly on these machines. This part fits a wide range of CRT models including the CRT36-23K-H, CRT36-24A-H, CRT36-25K-H, CRT48-25K-L, CRT48-25K-H, CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES, CRT48-31V-ES-E, and CRT36-24A-E ride-on trowels. Replacing worn or damaged fasteners with the correct OEM part ensures assemblies stay properly secured and aligned during operation.
Key Features
- OEM-Correct Shoulder Diameter and Thread Spec — manufactured to Wacker Neuson's exact M8 x 10 shoulder dimensions, ensuring the fastener seats and clamps correctly in its mating bore without slop or misalignment.
- Drop-In Installation — matches the original hole pattern and thread engagement on CRT36 and CRT48 assemblies, so the screw installs directly into its designed location without modification.
- Broad CRT Series Coverage — fits ten CRT36 and CRT48 ride-on concrete trowel configurations, from standard high-speed and low-speed variants to electronic steering models.
- Structural Integrity Under Vibration — the shoulder design provides a positive bearing surface that resists loosening from the continuous vibration generated during troweling cycles, keeping critical assemblies tight.
- Genuine Wacker Neuson OEM Part — sourced directly from Wacker Neuson, carrying the correct part number 5000117831 and meeting all original material and hardness requirements for this application.
A shoulder screw differs from a standard fastener in that it features a precision-ground unthreaded shank — the shoulder — between the head and the threaded section. This shoulder acts as a locating pin and bearing surface, controlling the position of mating components and allowing controlled rotational or sliding movement where required. On ride-on concrete trowels, shoulder screws are commonly used in pivot points, linkages, and guard assemblies where precise positional control matters. When a shoulder screw is worn, stripped, or replaced with an incorrect fastener, the assembly can shift out of alignment, introduce unwanted play, or fail to secure properly — affecting both the performance and safety of the trowel.
