Wacker Neuson 5100012665 Countersunk Screw

The Wacker Neuson 5100012665 is a genuine OEM Countersunk Screw designed for Wacker Neuson RC-series single-drum soil compactors and RD-series tandem rollers. As a factory-sourced component, it is manufactured to the exact material grade, thread specification, and head geometry required by the original equipment. This screw fits an extensive range of models spanning the RC50, RC70, and RC110 soil compactor families as well as the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller series, including standard, padfoot, cab, ROPS, DPF, open-drum, and combination configurations. Sourcing the correct OEM fastener ensures proper flush-seating, correct clamping load, and lasting hardware integrity in the assembly where it is installed.

Key Features

• Genuine OEM Thread and Head Geometry — Manufactured to the exact countersunk angle, thread pitch, and material specification called out by Wacker Neuson engineering, ensuring correct flush-seating and full clamping load every time.
• Direct Drop-In Replacement — Matches the OEM hole pattern and drive type so the screw seats flush without rework, shimming, or re-tapping of the receiving surface.
• Broad Model Coverage — A single part number covers the RC50, RC70, and RC110 single-drum soil compactor families and the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller series across multiple configurations, making it a versatile stock item for mixed fleets.
• Structural Integrity Where It Counts — A stripped, incorrect, or under-torqued countersunk fastener can allow panels, guards, or assemblies to work loose under compaction vibration; the correct OEM screw maintains the designed clamp force across demanding operating cycles.
• Verified Wacker Neuson Part Number — Cross-referenced against Wacker Neuson parts documentation as part number 5100012665, so you can order with confidence that this is the correct fastener for the application.

A countersunk screw is a fastener designed with a tapered head that sits flush with — or slightly below — the surface of the material it secures. On heavy compaction equipment like the RC and RD series, countersunk fasteners are used where a flush profile is required to prevent interference with moving components, protective covers, or mating surfaces. Using a fastener with the wrong head angle, thread pitch, or material grade can result in improper seating, reduced clamping force, and eventual loosening under the continuous vibration loads these machines generate. Replacing a worn or damaged screw with the correct OEM part restores the designed joint integrity and prevents secondary damage to the surrounding hardware or structure.
