The Wacker Neuson is a genuine OEM Self Tapping Screw, M4 X 0.7 designed for RD27-100 and RD27-120 series hydrostatic vibratory rollers. As a direct OEM replacement, is manufactured to the same dimensional and material specifications as the original hardware installed at the factory. This screw is confirmed compatible across multiple RD27-100 and RD27-120 machine configurations, including standard and traction control variants. Replacing worn or damaged fasteners with the correct OEM part keeps panels, covers, and components secured and aligned during operation.
Key Features
- Genuine OEM Hardware Specification — Manufactured to exact M4 X 0.7 thread pitch and head dimensions, ensuring the screw seats and drives correctly without thread stripping or misalignment.
- Self-Tapping Thread Design — Cuts its own mating thread on installation, making replacement straightforward in sheet metal and lightweight panel applications without a separate tap.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers across standard and traction control configurations, covering a wide range of machine numbers within the RD27 family.
- Structural Integrity at the Panel Level — A correctly torqued fastener keeps guards, covers, and housings properly secured; a loose or stripped screw can allow components to shift, vibrate free, or expose internal systems to debris and moisture.
- Direct OEM Sourcing — Supplied as a genuine Wacker Neuson part, meaning the part number, material grade, and finish match what was used in original assembly.
A self-tapping screw is a threaded fastener designed to form its own mating thread as it is driven into the base material, eliminating the need for a pre-tapped hole in many sheet metal and panel applications. In equipment like the RD27 series rollers, these screws are used to secure covers, guards, and ancillary components that are subject to constant vibration during compaction work. When a self-tapping screw becomes stripped, corroded, or sheared, the component it holds can loosen or shift, which may expose internal parts to damage or create operational noise and instability. Using the correct replacement screw with the right thread pitch and diameter ensures a firm, lasting connection that holds up under the vibration loads typical of roller operation.
