The Wacker Neuson is a genuine OEM Flange Lock Screw 5/16-18 X 3/4 designed for the CRT46KHN and CRT46KHO ride-on concrete trowels. Sourced directly from Wacker Neuson, this fastener meets the exact specifications of the original hardware used in production. It is confirmed to fit the CRT46KHN and CRT46KHO models, giving you confidence that this is the correct part for your machine. Having the right screw on hand keeps your trowel assembled to spec and ready for the next pour.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to the exact thread pitch, head geometry, and locking flange profile specified for the CRT46 series, ensuring consistent clamp load and resistance to loosening under vibration.
- Integrated Flange Lock Design — The built-in locking flange distributes clamping force evenly and resists self-loosening without requiring a separate washer or lock washer beneath the head.
- Direct Fitment for CRT46KHN and CRT46KHO — Verified as the correct replacement screw for both the CRT46KHN and CRT46KHO ride-on concrete trowel models.
- Maintains Structural Assembly Integrity — A worn, stripped, or incorrect fastener in a ride-on trowel can compromise critical joint assemblies; using the correct OEM screw restores the connection to its original holding strength.
- 5/16-18 X 3/4 Specification — Standard UNC thread form in the correct grip length for the application, so the screw engages the full thread depth intended in the original design.
A flange lock screw combines a standard hex-head cap screw with a wide, serrated flange integrated beneath the head. The flange acts like a built-in washer, spreading the clamping load over a larger surface area while the serrations bite into the mating surface to resist rotation and loosening — particularly important on ride-on concrete trowels, where continuous engine and rotor vibration can work conventional fasteners loose over time. When a screw of this type becomes stripped, corroded, or is replaced with an incorrect substitute, the joint it secures can lose clamping force, leading to movement, wear, or component misalignment that affects trowel performance and operator safety.
