The Wacker Neuson Stud Screw is a genuine OEM component designed for the RD40-130, RD45-140, RC50, RC70, RC110, and related tandem roller and single drum soil compactor series. Sourced directly through Wacker Neuson's authorized parts program, the delivers the exact thread specification, material grade, and dimensional tolerance required for a correct installation. This stud screw covers an extensive range of configurations including standard, cab, ROPS, DPF, VO, and US-market variants across multiple production series. Confirm your machine's model number against the fitment list to ensure this is the right part before ordering.
Key Features
- Genuine OEM Thread Specification — Manufactured to the exact thread pitch, diameter, and tensile strength called out in Wacker Neuson's engineering drawings, ensuring proper clamping force and secure fastening.
- Direct Drop-In Installation — Matches the original stud screw profile precisely, threading into existing receiver points without rework or modification to mating components.
- Broad Compactor and Roller Coverage — Fits RD40-130, RD45-140, RC50, RC50p, RC70, RC70p, RC70vo, and RC110 series machines, including DPF, CAB, ROPS, and US-market variants across multiple production generations.
- Maintains Structural Integrity Under Vibration — Compaction equipment operates under continuous high-frequency vibration; a correctly spec'd stud screw resists loosening and fatigue cracking that an undersized or worn fastener cannot.
- Authorized OEM Replacement — Carrying the Wacker Neuson part number 5100039073, this is the same fastener supplied in original equipment assembly, not a cross-referenced substitute.
A stud screw is a headless threaded fastener that anchors two or more components together by engaging threaded receivers on both ends or by accepting a nut on the exposed end. On compaction equipment like the Wacker Neuson RD and RC series, stud screws are used in critical assembly joints where a conventional bolt head would interfere with mating parts or where repeated removal and reinstallation must occur without damaging the base material. When a stud screw stretches, strips, or corrodes, the clamping load on that joint drops, which can lead to component movement, accelerated wear on surrounding parts, or outright mechanical failure during operation. Replacing a damaged or missing stud screw promptly with the correct OEM part restores the joint to its original load specification and keeps the assembly performing as intended.
