The Wacker Neuson is a genuine OEM Screw M12 x 40 Flat Head With Hole designed for the RS800 series single drum vibratory rollers, including the RS800, RS800A, RS800H, RS800V, and RSS800A. As a direct OEM replacement, this fastener is manufactured to the exact specification called out in the Wacker Neuson parts schema, ensuring correct thread pitch, head geometry, and hole configuration are maintained at reassembly. It is a verified fit for all major RS800 variants covered under machine numbers through. Keep a spare on hand so scheduled maintenance or field repairs on your RS800 series roller stay on track.
Key Features
- Exact OEM Thread and Head Specification — Manufactured to the precise M12 x 40 thread and flat-head-with-hole geometry specified by Wacker Neuson, ensuring correct torque transfer and flush seating at the mounting point.
- Drop-In Replacement for RS800 Series Rollers — Replaces the original fastener position for position on RS800, RS800A, RS800H, RS800V, and RSS800A single drum vibratory rollers without rework or re-drilling.
- Broad RS800 Family Coverage — A single part number covers multiple RS800 variants, including walk-behind and engine-equipped configurations, simplifying parts stocking for fleet operators.
- Structural Integrity Under Vibration Load — Single drum rollers generate continuous high-frequency vibration during compaction; a correctly specified OEM fastener resists loosening and maintains clamping force where an undersized or mismatched screw would not.
- Genuine Wacker Neuson OEM Part — Sourced directly through authorized Wacker Neuson supply channels, carrying part number 5000077255 for straightforward verification against your machine's parts breakdown.
A flat-head fastener with a drilled hole — sometimes called a wire-lock or safety-wire screw — serves two roles in a vibratory machine. The flat countersunk head seats flush with the surrounding surface, preventing protrusions that could snag or interfere with adjacent components. The cross-drilled hole allows safety wire or a locking device to be threaded through, mechanically preventing the screw from backing out under the sustained vibration that single drum rollers produce during compaction passes. When this fastener is missing, damaged, or replaced with a non-drilled equivalent, the assembly loses its anti-rotation protection, increasing the risk of joint loosening over time and potentially causing component misalignment or detachment during operation.
