The Wacker Neuson is a genuine OEM Bolt M8 X 1.25 designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. As a factory-sourced fastener, the is manufactured to the exact thread pitch, head dimensions, and tensile grade specified for these machines — ensuring a secure, correctly torqued connection every time. This bolt fits across multiple serial number configurations of the RD27-100 and RD27-120, including traction control and standard variants. When sourcing hardware for a precision compaction machine, using the correct OEM-specified fastener is the straightforward choice.
Key Features
- Correct Thread Specification — M8 x 1.25 thread pitch matches the factory-tapped holes on the RD27 series, preventing cross-threading or fastener failure under vibration load.
- Genuine OEM Sourcing — Manufactured to Wacker Neuson's original tensile and dimensional specification, ensuring the bolt performs as intended in a high-vibration roller application.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers across standard and traction control configurations.
- Vibration-Environment Integrity — A properly specified bolt maintains clamping force through continuous drum vibration; an undersized or incorrect-grade substitute can back out or shear, leading to component loosening mid-operation.
- Direct OEM Reference — Order by part number 5000162021 for exact fitment confirmation — no cross-referencing or guesswork against aftermarket hardware catalogs.
A fastener of the correct metric thread pitch and tensile grade is critical on vibratory compaction equipment, where drums and drive components generate continuous cyclical stress. The M8 x 1.25 thread designation defines both the bolt's diameter and pitch — meaning it will only engage correctly with an M8-tapped hole at 1.25 mm per thread. Using an incorrect pitch or a lower-grade substitute risks stripped threads, loss of clamping force, or fastener fatigue over time. On a tandem roller like the RD27 series, where structural and drivetrain components must remain securely fixed through sustained compaction work, replacing worn or damaged hardware with the specified OEM bolt maintains the integrity of the assembly it secures.
