The Wacker Neuson 5100010091 is a genuine OEM Cheese Head Screw designed for the DPU and BPU series reversible vibratory plate compactors, including DPU6555, DPU5545, DPU4545, and BPU 4045A and BPU 5545A models, as well as the APU series battery-powered vibratory plates. As a genuine OEM component, part 5100010091 is produced to the exact material grade and dimensional specification of the original hardware, ensuring a direct, tool-matched installation without guesswork. This screw services an exceptionally wide range of compaction equipment across the DPU, BPU, and APU families, making it a smart stocking item for shops and fleet operators running multiple machine configurations. Confirm your model variant against the fitment list before ordering to ensure this is the correct fastener for your application.
Key Features
- Genuine OEM Material Grade — Manufactured to the exact tensile and hardness specifications required for a structural fastener in a high-vibration compaction environment, where undertorqued or incorrect hardware can back out under load.
- Exact Thread Form and Head Geometry — The cylindrical cheese head profile provides the correct bearing surface and driver engagement for the original torque spec, installing cleanly without shimming or substitution.
- Broad DPU, BPU, and APU Compatibility — Fits confirmed variants across the DPU6555, DPU5545, and DPU4545 diesel reversible plate series, BPU 4045A and BPU 5545A gasoline reversible plates, and multiple APU battery-powered vibratory plate models.
- Vibration-Resistant Holding Power — A correctly specified fastener maintains clamping force through continuous compaction cycles; a mismatched or worn screw risks progressive loosening, component shift, and accelerated wear on surrounding parts.
- Wide Variant Coverage — Supports US-market, standard, and special-configuration model suffixes within the DPU6555 and DPU5545 families, reducing the number of individual fastener SKUs a shop needs to carry.
A cheese head screw is a machine fastener characterized by a cylindrical head with a flat top and straight sides, providing a larger bearing surface than a standard pan head while keeping a low-profile form suited to recessed or close-tolerance assemblies. In vibratory plate compactors, structural fasteners like this one are subjected to sustained, high-frequency vibration during operation, which places continuous stress on the clamping joint. When a fastener of this type fails — through corrosion, fatigue, or substitution with an incorrect grade — it can allow mated components to shift, leading to accelerated wear, misalignment, and potential damage to the surrounding assembly. Using the correct OEM fastener with the proper thread engagement and material specification maintains the integrity of the joint throughout the service life of the machine.
