The Wacker Neuson M8 X 40 Hx Serr Flg Screw is a genuine OEM fastener designed for the CRT48-31V series ride-on concrete trowels, including the CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES-E, and CRT48-31V-ES models. As a direct factory replacement, this screw meets the exact torque retention and dimensional standards required for proper reassembly of your trowel. Sourcing the correct fastener by part number ensures structural integrity at the connection point and eliminates the guesswork of matching thread pitch, shank length, and flange geometry. Keep this part number on hand for scheduled maintenance and field repairs on your CRT48-31V trowel.
Key Features
- Correct Thread Engagement: — M8 x 40mm hex serrated flange specification matches the original fastener exactly, ensuring full thread engagement and proper clamping force at the installation point.
- Serrated Flange Locking: — The integrated serrated flange bites into the mating surface under torque, resisting loosening from the vibration inherent in ride-on trowel operation.
- Genuine OEM Sourcing: — Produced to Wacker Neuson's original engineering drawings, this screw carries the same material grade and surface treatment as the fastener installed at the factory.
- Broad CRT48-31V Compatibility: — Confirmed fitment across the CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES-E, and CRT48-31V-ES ride-on trowel variants.
- Drop-In Replacement: — Installs directly into the existing tapped bore with standard hex tooling — no re-tapping, drilling, or additional hardware required.
A hex serrated flange screw combines the function of a standard hex bolt with an integrated locking washer. The serrations stamped into the underside of the flange grip the clamped surface when tightened, creating mechanical resistance to loosening — a critical quality in rotating or vibrating assemblies such as ride-on concrete trowels. When this fastener stretches, strips, or loses its serration profile, the joint it secures can shift or come apart during operation, leading to misalignment, accelerated wear on surrounding components, or a potential safety concern. Replacing a worn or damaged screw with the correct OEM part restores the designed clamping load and keeps the assembly performing as intended.
