Wacker Neuson 5000211795 Corrugated Head Screw

The Wacker Neuson is a genuine OEM Corrugated Head Screw designed for the DPU and BPU series reversible vibratory plate compactors. This fastener is a direct OEM replacement sourced from Wacker Neuson, ensuring the correct thread form, head profile, and material grade for the application. Verified fitment spans a wide range of DPU and BPU models including the DPU6555, DPU5545, DPU4545, DPU4045, DPU5260, DPU6275, DPU80, DPU90, DPU110 series, and select BPU5260 and BPU6275 models. Having the right fastener on hand keeps your compactor assembly intact and prevents costly disassembly caused by incorrect hardware.

Key Features

• Genuine OEM Thread and Head Spec — Manufactured to Wacker Neuson's exact corrugated head profile and thread specification, ensuring proper torque retention in the compactor housing without stripping or loosening under vibration.
• Drop-In Replacement — Matches the original fastener's dimensions and drive type for a straightforward swap during scheduled maintenance or field repair on DPU and BPU plate compactors.
• Broad DPU and BPU Fitment — Covers an extensive range of reversible vibratory plate compactor models across the DPU6555, DPU5545, DPU4545, DPU4045, DPU5260, DPU6275, DPU80, DPU90, DPU110 families, plus BPU5260 and BPU6275 variants.
• Vibration-Resistant Fastening — The corrugated head design provides mechanical locking resistance under continuous vibratory loads, maintaining structural integrity across demanding compaction cycles.
• Correct Hardware Prevents Assembly Damage — Using the OEM-specified screw avoids mismatched thread engagement that can damage housings, panels, or mating components — protecting more costly surrounding parts.

A corrugated head screw is a specialized fastener whose serrated or ridged underhead geometry bites into the mating surface as it is tightened, creating a mechanical lock that resists loosening from vibration. On reversible vibratory plate compactors, which generate continuous high-frequency oscillation during operation, standard smooth-bearing fasteners are prone to backing out over time. The corrugated head addresses this by increasing friction and grip at the contact face. When this screw is missing, damaged, or replaced with an incorrect fastener, panels and covers can work loose, leading to component exposure, accelerated wear of surrounding hardware, or unplanned downtime in the field.
