The Wacker Neuson is a genuine OEM Hexagonal Flange Head Screw designed for a wide range of Wacker Neuson tandem rollers, portable generators, and related equipment assemblies. Sourced directly from Wacker Neuson, this fastener matches the exact thread pitch, head geometry, and flange diameter specified for the original build. Fitment spans the RD12, RD16, and RD27 tandem roller series, the GP2600 portable generator, APT4 series pumps, and the HTC15 trench roller. Keeping the correct OEM fastener in place ensures structural integrity across critical assemblies — from drum and seat components to hydraulic and fuel systems.
Key Features
- OEM-Spec Flange Geometry — The integrated flange distributes clamping load evenly, eliminating the need for a separate washer and maintaining the torque retention the original design requires.
- Direct Drop-In Replacement — Matches the original thread specification and head profile for the 5000163948 position, seating flush without rework or thread chasing.
- Broad Tandem Roller Coverage — Compatible with multiple configurations of the RD12, RD16, and RD27 tandem roller series, including standard, foldable ROPS, and Pro variants.
- Cross-Equipment Versatility — Also fits GP2600 portable generators, APT4S and APT4T pump assemblies, and the HTC15 trench roller, making it a useful fastener to stock on mixed Wacker Neuson fleets.
- Genuine OEM Traceability — Supplied under the original Wacker Neuson part number 5000163948, so you can confirm the correct part against your machine's parts diagram with confidence.
A hexagonal flange head screw combines a standard hex bolt head with a wide, integrated bearing flange at its base. The flange acts as a built-in washer, spreading clamping force over a larger surface area to prevent fastener pull-through and reduce the risk of loosening under vibration — a critical property on compaction and roller equipment that operates under constant dynamic load. When this screw is missing, stripped, or substituted with a non-spec fastener, the joint can lose proper preload, leading to loosened assemblies, accelerated wear on mating components, or structural failure at the connection point. Using the correct OEM screw ensures the joint behaves as engineered across the full service life of the assembly.
