Wacker Neuson 5100005815 Corrugated Head Screw

The Wacker Neuson Corrugated Head Screw is a genuine OEM corrugated head screw designed for the DPU80r and DPU90r series vibratory plates, including the DPU80rLec670, DPU80rLec770, DPU80rLem670, DPU80rLem770, DPU90rLec770 US, DPU90rLem770 US, and the DPU 80/110 KMAT. Sourced directly from Wacker Neuson, this is the exact same part installed during original equipment assembly — no guesswork on fit or specification. Whether you're completing a scheduled service or replacing a worn fastener, part number keeps your compaction equipment running as intended across both the Lec and Lem engine variants.

Key Features

• OEM Thread and Head Profile: — Corrugated head geometry matches the original specification, ensuring consistent clamping force and resistance to vibration-induced loosening on compaction equipment.
• Drop-In Replacement: — Installs directly into the same mounting position as the factory fastener with no re-drilling, re-tapping, or hardware modification needed.
• Broad DPU Series Coverage: — Confirmed fit across DPU80r Lec/Lem 670 and 770 variants, DPU90r Lec/Lem 770 US models, and the DPU 80/110 KMAT vibration plate.
• Vibration-Resistant Fastening: — The corrugated head design provides mechanical resistance to backing out under the high-frequency vibration loads typical of plate compactor operation, keeping assemblies tight through extended use.
• Genuine Wacker Neuson Part: — Supplied as authentic OEM stock under part number 5100005815, so the material grade, head dimensions, and thread form are exactly what the machine was engineered to accept.

A corrugated head screw uses a ridged or wavy pattern on the underside of the screw head to grip the mating surface and resist rotational loosening — a critical characteristic on machinery subject to constant vibration. On vibratory plate compactors like the DPU80r and DPU90r series, standard smooth-head fasteners can gradually work loose under operating loads, leading to component misalignment or structural failure at the fastening point. Using the correct corrugated head screw maintains the integrity of the assembly and prevents the progressive damage that a backed-out or missing fastener can cause over time.
