Wacker Neuson 5000157051 Set Screw M8X12 Dog Pt

The Wacker Neuson Set Screw M8X12 Dog Pt is a genuine OEM fastener designed for the CT36 and CT48 series walk-behind concrete power trowels. Sourced directly from Wacker Neuson, this set screw meets the exact specifications used in original production, ensuring a correct installation every time. It is compatible across a wide range of CT36 and CT48 trowel models, including the CT36-5A, CT36-6, CT36-8A, CT36-9, CT36-400E, CT36-X, CT48-8A, CT48-9, CT48-11A, and CT48-13A-V. When a set screw works loose or strips out, replacing it promptly with the correct OEM part keeps critical trowel components properly secured and the machine running as intended.

Key Features

• Genuine OEM Specification: — Manufactured to the exact thread pitch, point geometry, and hardness grade specified by Wacker Neuson for this application — not a generic substitute.
• Dog-Point Design for Positive Location: — The dog-point tip seats into a mating hole or groove to lock rotating or sliding components in precise alignment, preventing unwanted movement under load.
• Drop-In Installation: — M8x12 dimensions match the original fastener exactly, threading directly into the existing tapped bore without rework or thread chasing.
• Broad CT-Series Compatibility: — Fits a wide span of CT36 and CT48 walk-behind power trowel variants, covering multiple engine and voltage configurations across the lineup.
• Protects Surrounding Components: — A correctly torqued set screw prevents shaft or hub movement that can accelerate wear on blades, gearbox components, and drive assemblies — keeping repair costs contained.

A set screw is a headless fastener threaded fully through a collar, hub, or housing to bear against — or seat into — the shaft or component beneath it, holding it in a fixed position. In a concrete power trowel, set screws are used to secure rotating assemblies so that torque transfers cleanly from the drive without slippage. When a set screw loosens or fails, the component it retains can shift under the vibration and load of troweling work, causing accelerated wear, misalignment, or outright loss of the secured part. Replacing a worn or damaged set screw with the correct OEM part restores positive retention and protects the integrity of the assembly it serves.
