The Wacker Neuson 5100009777 is a genuine OEM Cheese Head Screw designed for the DPU80, DPU90, and DPU110 series reversible vibratory plate compactors, as well as AR series external concrete vibrators. As a genuine OEM component, this screw is manufactured to the exact material grade and dimensional tolerances specified by Wacker Neuson, ensuring a secure, consistent fit within the assembly it fastens. It is a direct replacement for units across the DPU80Lec, DPU80Lem, DPU90Lec, DPU90Lem, DPU110Lec, DPU110Lem, and their reverse-drive counterparts, covering both standard and US-market variants. Verified against part number 5100009777, this fastener keeps your plate compactor or external vibrator running correctly without the guesswork of sourcing a non-specified substitute.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Wacker Neuson's specified material hardness and thread tolerance, ensuring the clamping load this screw must deliver is maintained under compaction vibration cycles.
- Drop-In Replacement — Matches the original thread pitch, head diameter, and drive type, so it seats and torques correctly without reworking the mating components.
- Broad DPU Series Coverage — Fits DPU80, DPU90, and DPU110 forward and reversible plate compactors in both Lec and Lem configurations, including US-market models.
- AR Vibrator Compatible — Also confirmed for AR 43/6/250, AR 43/3/230v, AR 43/3/400, and AR 43/6/042 external concrete vibrators, making this a multi-application fastener across the Wacker Neuson lineup.
- Vibration-Resistant Retention — Cheese head screw geometry provides a larger bearing surface than a standard pan head, helping maintain clamp force in high-vibration compaction and vibration applications where fastener loosening is a common failure point.
A cheese head screw is a precision fastener characterized by its cylindrical, flat-topped head with a large bearing surface area, used to secure components within an assembly where a strong, stable clamp load is required. In vibratory plate compactors and external concrete vibrators, fasteners like the 5100009777 are subjected to continuous mechanical vibration during operation, making the correct head geometry, thread specification, and material grade critical to maintaining structural integrity. When a fastener of the wrong specification is used — or when an original screw stretches or strips from wear — it can result in component loosening, misalignment, or accelerated wear to surrounding parts.
