The Wacker Neuson M12 Hex Cap Nut is a genuine OEM fastener designed for the WP1540, WP1550, WP2050, WPP1540, WPP1550, and WPU1550 series plate compactors. Sourced directly from Wacker Neuson, this hex cap nut meets the exact dimensional and material standards used in original assembly, ensuring a secure, torque-rated connection every time. It is compatible across a broad range of single-direction and reversible plate compactor configurations in the WP and WPP families, making it a straightforward service item for fleet operators and technicians alike.
Key Features
- OEM-Grade Thread Integrity — Manufactured to Wacker Neuson's original M12 thread specification, so you get the correct engagement depth and clamping load without guesswork.
- Drop-In Installation — Matches the original fastener profile exactly, threading directly onto existing studs and bolted joints with no chasing or rework needed.
- Broad Plate Compactor Coverage — Fits WP1540, WP1550, WP2050, WPP1540, WPP1550, and WPU1550 series machines, including A, W, Aw, Ww, RAW, and US market variants.
- Secure Fastening Under Vibration — Plate compactors operate under continuous high-frequency vibration; a correctly specified hex cap nut maintains clamp force and prevents joint loosening that can lead to component damage or misalignment.
- Genuine Wacker Neuson Part — Part number 5000402483 is an authorized OEM component, so you can be confident it matches the original production specification for your machine.
An M12 hex cap nut is a fully enclosed, internally threaded fastener used to secure bolted assemblies across the plate compactor's frame, exciter, and drivetrain components. The hex cap design provides a bearing surface that distributes clamping load evenly while the closed end protects the thread from contamination and impact damage. When a hex cap nut becomes stripped, corroded, or loses its seating torque under vibration, the joint it secures can work loose — leading to component shift, accelerated wear on adjacent parts, or structural fastener failure during operation.
