The Wacker Neuson Spider Screw is a genuine OEM component designed for the CT24-4A and CT24-230E series walk-behind concrete power trowels. As a direct factory replacement, this part meets the exact specifications of the original hardware used in Wacker Neuson's 24-inch trowel lineup. Fitment covers both the CT24-4A and CT24-230E models, including their EU-configured variants, so verify your model number before ordering. Sourcing the correct OEM spider screw ensures the trowel's finishing blades remain securely and evenly positioned during operation.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the same thread specification and material grade as the original fastener, ensuring consistent clamping force at the spider assembly.
- Direct Drop-In Replacement — Threads directly into the existing spider hub with no modifications to the surrounding assembly, matching the original installation pattern.
- Broad CT24 Series Coverage — Compatible with CT24-4A, CT24-230E, and their EU-market variants, making this a versatile stock item for fleets running multiple 24-inch walk-behind trowels.
- Blade Alignment You Can Count On — A correctly torqued spider screw keeps finishing blades at a uniform pitch angle; a stripped or missing fastener causes uneven blade contact and a poor surface finish.
- OEM Part Number Verified — Part number 5000174945 cross-references directly to Wacker Neuson's parts system, so you receive the correct component without guesswork.
The spider screw secures the trowel blade arms to the spider hub at the center of the power trowel's rotor assembly. It works alongside the other spider hardware to hold each blade arm at the correct pitch angle, which directly controls how the blades contact and finish the concrete surface. When a spider screw loosens, strips, or fails, blade pitch becomes inconsistent across the rotor, leading to uneven finishing patterns, increased operator effort, and potential damage to the blade arms or spider casting.
