The Wacker Neuson Socket Head Screw is a genuine OEM component designed for the RD7A, RD7H, RD7He, and RD7Ye series tandem and walk-behind rollers. As a direct Wacker Neuson OEM part, is manufactured to the same standards as the original hardware installed at the factory, ensuring a consistent, secure fit within the assembly. This screw is confirmed compatible across a wide range of RD7 series configurations, including both standard and emissions-compliant variants. When sourcing fasteners for compaction equipment, using the correct OEM part eliminates the guesswork around thread pitch, head geometry, and torque capacity.
Key Features
- Correct Thread and Head Geometry — Manufactured to OEM specification for thread pitch and socket head dimensions, ensuring full engagement with the mating components during installation.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this is the same screw used in original assembly — not an approximation.
- Broad RD7 Series Compatibility — Fits RD7A, RD7H, RD7He, and RD7Ye tandem rollers and walk-behind rollers across multiple build configurations and serial ranges.
- Structural Integrity Under Vibration — Socket head fasteners used in compaction equipment must resist loosening under continuous vibration; the OEM specification ensures correct material hardness and thread form for this environment.
- Verified Part Number — Cross-reference 5200021852 against your machine's parts diagram before ordering to confirm the correct application within your specific assembly.
A socket head screw is a threaded fastener with a cylindrical head and an internal hex (Allen) drive socket, designed to be tightened with a hex key or socket driver. In compaction equipment like the RD7 series rollers, these screws are used to secure critical components where a flush or recessed fastener head is required and where high clamping force must be maintained under persistent vibration and load. A worn, stripped, or incorrect screw can lead to component loosening, misalignment, or structural failure in the assembly it holds — making it important to replace with the correct OEM part that matches the original thread specification and material grade.
