The Wacker Neuson is a genuine OEM Screw M4 X 40 Flat Head designed for RD16-90 and RD16-100 series tandem vibratory rollers. As a factory-sourced fastener, it is manufactured to the exact thread pitch, head profile, and material specification required for the original assembly. This screw is confirmed for multiple RD16-90 configurations, including the standard Vibratory Roller, Hydrostatic Vibratory Roller (IRH), and Tandem Roller variants, as well as the RD16-100 and RD16-100 Hydrostatic Vibratory Roller. When a fastener in a precision assembly wears, strips, or is lost during service, replacing it with the correct OEM part ensures the mating components seat properly and the assembly maintains its designed integrity.
Key Features
- Exact Thread and Head Specification — M4 x 40 flat-head profile matches the original countersunk seating geometry, ensuring flush installation without proud edges or assembly misalignment.
- Genuine OEM Sourcing — Sourced directly through Wacker Neuson, this fastener meets the same material grade and surface treatment used on the original production line, not an approximation.
- Broad RD16 Series Coverage — Fits RD16-90 (standard, IRH hydrostatic, and tandem configurations) and RD16-100 (standard and hydrostatic variants), covering the full RD16 tandem roller family.
- Maintains Assembly Torque and Clamping Load — Correct thread engagement depth and shank length are critical in roller assemblies where vibration is constant; an undersized or incorrect fastener can back out under operating loads.
- Direct Service Drop-In — Replaces part 5000165411 on a one-for-one basis with no modification to the mating hardware, keeping teardown time to a minimum during scheduled or corrective maintenance.
A flat-head machine screw like the Wacker Neuson 5000165411 is used in assemblies where the fastener head must sit flush with or below the surface of the mating component — common in housings, guards, panels, and structural brackets where a protruding head would interfere with adjacent parts or clearance zones. In a tandem vibratory roller environment, fasteners are subjected to continuous vibration, making correct thread specification and material grade essential to maintaining clamp load over time. When the wrong screw is used — whether the wrong length, head type, or thread class — it can lead to loosening, damaged threads in the host material, or component misalignment that accelerates wear elsewhere in the assembly.
