Wacker Neuson 5100012978 Stud Bolt

The Wacker Neuson Stud Bolt is a genuine OEM stud bolt designed for a broad range of Wacker Neuson RD series tandem rollers and RC series single drum soil compactors. Sourced directly from Wacker Neuson, this stud bolt meets the exact dimensional and material specifications of the original hardware installed at the factory. It fits an extensive lineup spanning the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, as well as the RC50, RC70, and RC110 single drum soil compactor series — covering standard, cab, open ROPS, canopy, DPF, and electric variants. When critical fasteners like this stud bolt are worn, stretched, or damaged, proper clamping force and structural integrity can be compromised, making a like-for-like OEM replacement the right call.

Key Features

• OEM-Grade Fastener Material — Manufactured to Wacker Neuson's original tensile and thread-pitch specifications, ensuring consistent clamping load across every application.
• Direct Bolt-In Replacement — Matches the thread form, shank diameter, and length of the original stud bolt for straightforward installation without rework or modification.
• Broad Series Compatibility — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers as well as RC50, RC70, and RC110 single drum soil compactors across multiple configuration variants including DPF, cab, ROPS, open, and electric models.
• Structural Integrity Maintained — A correctly torqued, undamaged stud bolt holds assemblies in precise alignment; a compromised stud can lead to joint movement, vibration damage, and premature wear on surrounding components.
• Genuine Wacker Neuson Part — Carries the full backing of Wacker Neuson's OEM supply chain, so you can be confident part number 5100012978 is exactly what your machine was built with.

A stud bolt is a fully threaded fastener used to clamp two or more components together, typically by threading into one mating surface and securing with a nut on the opposite end. On compaction equipment like Wacker Neuson tandem rollers and soil compactors, stud bolts are found in high-vibration assemblies where maintaining precise, repeatable clamping force is critical to keeping components properly seated during operation. When a stud bolt stretches, strips, or corrodes, it can no longer hold the specified torque, leading to loosening under load, potential misalignment of joined components, and accelerated wear or damage to the surrounding assembly.
