Wacker Neuson 5100012405 Hexagon Nut

The Wacker Neuson 5100012405 is a genuine OEM Hexagon Nut designed for the RC and RD series single-drum soil compactors and tandem rollers. Sourced directly from Wacker Neuson, this fastener meets the exact specifications of the original hardware installed at the factory. Fitment covers a wide range of models including the RC50, RC70, RC110, RD18, RD24, RD27, RD28, RD40, and RD45 series, spanning standard, DPF, CAB, and ROPS configurations. Replacing a worn or missing fastener with the correct OEM part ensures structural integrity and keeps your machine performing as intended.

Key Features

• Correct Thread Form and Dimensional Accuracy — Manufactured to OEM specification so the nut seats flush, threads cleanly, and torques to the correct value without risk of cross-threading or stripping.
• Genuine OEM Part — Supplied by Wacker Neuson as part number 5100012405, ensuring the material grade, hardness, and finish match what was installed at production.
• Broad Model Coverage — Verified fit across the RC50, RC70, and RC110 single-drum soil compactor families and the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller series, including DPF, CAB, and ROPS variants.
• Structural Reliability — A correctly torqued fastener maintains clamping load on critical joints; a damaged or incorrect nut can lead to loose assemblies, accelerated wear, and unplanned service intervals.
• Direct-Replacement Hardware — Installs in place of the original without rework, fitting the same threaded stud or bolt pattern as the production part it replaces.

A hexagon nut is a fundamental threaded fastener used throughout heavy equipment to secure components at bolted joints, mounting flanges, and structural connections. It works in conjunction with a bolt or stud to develop and hold the clamping force that keeps assemblies rigid under vibration and load — both of which are constant factors in compaction and rolling equipment. When a nut is lost, damaged, or replaced with an incorrect grade, the joint can lose clamping force, causing movement between mated surfaces that leads to accelerated wear, fatigue cracking, or full separation of the assembly.
