The Wacker Neuson 5100012784 is a genuine OEM Cheese-Head Screw designed for the RD-series tandem rollers and RC110 single-drum soil compactors. As a factory-sourced fastener, it meets the exact material grade, thread specification, and head geometry required by Wacker Neuson engineering for these machines. This screw fits a broad range of configurations across the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, as well as RC110 ROPS and RC110 CAB variants. Ordering by part number 5100012784 ensures you receive the correct fastener the first time, with no guesswork on sizing or compatibility.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact material hardness and thread tolerance specified by Wacker Neuson, so the fastener holds torque load correctly in the assembly.
- Correct Head Profile for Recessed Access — The cheese-head (cylindrical-head) form provides maximum bearing surface and a deep drive socket for secure installation in tight or recessed mounting points.
- Broad RD-Series and RC110 Coverage — Verified for RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers across multiple build variants, plus RC110 ROPS and CAB single-drum compactors.
- Direct OEM Sourced Replacement — Sourced through Wacker Neuson's parts supply chain, matching the thread pitch, shank length, and head dimensions of the original fastener without any rework at installation.
- Prevents Assembly Loosening and Joint Failure — A correctly spec'd fastener maintains clamping force under vibration-heavy compaction cycles; an undersized or mismatched screw risks backing out and damaging surrounding components.
A cheese-head screw is a cylindrical-headed machine screw used to secure components within an assembly where a large, flat bearing surface and deep socket drive are needed. In vibration-intensive equipment like tandem rollers and single-drum compactors, fasteners are subjected to constant cyclical stress, making correct material grade and thread fit critical. When a fastener is worn, stripped, or replaced with an incorrect substitute, the clamping joint can loosen progressively, leading to component movement, accelerated wear on surrounding parts, and potential assembly failure during operation.
