The Wacker Neuson is a genuine OEM Stud M8 X 3.375 8.8 Pl designed for the RT560, RT820, and RT820HT Vibratory Trench Rollers. Sourced directly from Wacker Neuson, this stud meets the original engineering specification for these remote-controlled articulated trench rollers. It is a direct-fit replacement that installs exactly as the factory-original hardware, with no modification needed to surrounding components. Confirmed fitment spans multiple serial number ranges across the RT560, RT820, and RT820HT model lines.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to the exact M8 x 3.375 thread dimensions and 8.8 tensile grade specified by Wacker Neuson, ensuring correct clamping force and thread engagement in the application.
- Direct Replacement Hardware — Matches the original stud in thread pitch, shank length, and strength class, allowing straightforward installation into existing threaded bores without re-tapping or shimming.
- Broad RT-Series Fitment — Verified for use across RT560, RT820, and RT820HT Vibratory Trench Roller variants, covering multiple production serial number ranges.
- Structural Load Rating — The 8.8 property class rating confirms the stud is engineered to handle the dynamic loads and vibration stresses present in trench roller operation, where fastener fatigue is a real failure risk.
- Corrosion-Resistant Finish — The Pl (plain/phosphate) surface treatment provides a base level of corrosion resistance suited to the demanding, dirt- and moisture-exposed environments where trench rollers work.
A stud is a headless threaded fastener that remains permanently seated in one component while a nut is threaded onto the exposed end to clamp a mating part in place. In vibratory equipment like trench rollers, studs are subjected to continuous oscillation and mechanical stress that can cause undertorqued or worn fasteners to loosen or fail, leading to misalignment of structural components or unsafe operation. Replacing a damaged or stripped stud with the correct OEM-grade part restores the clamping integrity the assembly was designed around.
