Wacker Neuson 5000074025 Set Screw M8 X 12 Cuppoint

The Wacker Neuson is a genuine OEM Set Screw M8 X 12 Cuppoint designed for the CT-series walk-behind concrete power trowels, including CT30, CT36, and CT48 models. As a genuine Wacker Neuson part, is manufactured to the same specification as the original hardware installed at the factory, ensuring correct thread engagement and holding force in your trowel's assembly. This set screw fits an extensive range of CT-series machines — from 30-inch to 48-inch deck configurations — covering both gasoline and diesel-powered variants across multiple production runs.

Key Features

• Genuine OEM Thread Specification: — M8 x 12 cuppoint geometry matches the original fastener exactly, delivering consistent clamping force and bite without distorting the mating surface.
• Drop-In Hardware Fit: — Threaded to the same pitch and class as the factory-installed screw, so it installs directly into existing tapped bores on the trowel assembly without rework.
• Broad CT-Series Coverage: — Verified fitment across CT30, CT36, and CT48 walk-behind power trowel families, including AGP, ADP, AGT, ADT, BDT, and BDP variants in standard and CE configurations.
• Maintains Secure Component Retention: — A properly torqued cuppoint set screw bites into the shaft or bore it contacts, locking the target component in position; a stripped or missing screw allows unwanted movement that accelerates wear on surrounding parts.
• Sourced Direct from Wacker Neuson: — Backed by Wacker Neuson's OEM parts program, giving you full confidence that part number 5000074025 is the correct replacement for your machine's service record.

A set screw is a headless fastener that threads fully into a tapped hole and presses its cuppoint tip against a shaft, collar, or mating surface to lock a component in place without protruding beyond the surrounding material. On a walk-behind concrete power trowel, set screws are used throughout the drivetrain and blade guard assemblies to secure rotating or adjustable components against vibration and operational loads. When a set screw loosens, backs out, or fails, the part it was holding can shift, creating slop in the assembly that leads to accelerated wear, misalignment, or component damage — making timely replacement with the correct hardware essential to keeping the trowel operating as designed.
