The Wacker Neuson Cheese-Head Screw is a genuine OEM cheese-head screw designed for the RD18, RD40, and RD45 series tandem rollers. As a direct OEM component sourced from Wacker Neuson, it meets the exact material and dimensional specifications of the original hardware used on these machines. This screw fits an extensive range of configurations across the RD18-80, RD18-100, RD40-130, and RD45-140 model families — including standard, C, O, DPF, US, and SE variants — giving you confidence that is the right part regardless of which configuration you're running. Having the correct fastener on hand keeps your roller assembly tight and properly secured through the demanding cycles of compaction work.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's original hardness and thread specification, ensuring the screw seats and torques correctly without stripping or backing out under vibration.
- Direct Drop-In Installation — Matches the original thread pitch, shank diameter, and head profile for straightforward installation using standard tooling — no chasing threads or reworking mounting points.
- Broad Series Coverage — Fits RD18-80, RD18-100, RD40-130, and RD45-140 tandem rollers across standard, C, O, DPF, US, and SE configurations, consolidating one part number across your fleet.
- Vibration-Resistant Fastening — A correctly spec'd cheese-head screw maintains clamping force through the continuous vibration cycles that tandem rollers produce, preventing joint loosening over extended compaction runs.
- Verified OEM Part Number — Part number 5100016820 is confirmed against Wacker Neuson's own parts documentation, so you're ordering the exact replacement called out in the service manual.
A cheese-head screw is a precision fastener identified by its cylindrical, flat-topped head — a profile that allows a firm seating surface in recessed or countersunk applications while keeping a low overall height. In compaction equipment like tandem rollers, fasteners like the 5100016820 are critical to maintaining the structural integrity of assemblies that experience constant vibration and dynamic loading during operation. When a fastener of the wrong specification is used — or when an original screw becomes worn, stripped, or corroded — it can compromise joint clamping force, leading to component movement, accelerated wear on mating parts, and potential assembly failure in the field.
