The Wacker Neuson Stud Bolt is a genuine OEM component designed for the RD27-120C and RD28-120C series tandem rollers, including the RD28-120c DPF and RD28e-120c variants. As a factory-sourced part, it meets the exact material and dimensional standards set by Wacker Neuson, ensuring a correct, no-compromise installation. This stud bolt is a direct replacement for the original hardware across all listed RD27 and RD28 series models, giving you confidence that the part will fit and function as intended.
Key Features
- Genuine OEM Thread and Material Spec — Manufactured to Wacker Neuson's exact tensile and threading standards, so the bolt engages and torques correctly without risk of stripping or misalignment.
- Direct Drop-In Replacement — Matches the original stud bolt profile and thread pitch, allowing straightforward installation without rework or modification to the surrounding hardware.
- Broad RD Series Compatibility — Fits the RD27-120C, RD28-120C, RD28-120c DPF, and RD28e-120c tandem rollers, covering multiple production variants within the RD27 and RD28 family.
- Maintains Structural Integrity — A correctly fitted stud bolt holds mated components under the vibration and compaction loads common to roller operation; a worn or failed fastener can allow joint movement and accelerated component damage.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so part number 5100012379 matches the original documentation and service records for your machine.
A stud bolt is a fully threaded fastener used to clamp two or more components together, typically threading into one part while a nut is tightened from the opposite end. On a tandem roller, stud bolts are used in assemblies that must remain securely joined under continuous mechanical stress and vibration — such as drum housings, frame attachments, and drive components. When a stud bolt stretches, corrodes, or fails, the clamping force across that joint is lost, which can lead to looseness, misalignment, and damage to adjacent components.
