The Multiquip 40028200 Hex Nut M5 is a genuine OEM fastener designed for RAMMAX walk-behind roller models including the RW1404, RW1404MR, and RW1504HF. As an OEM-sourced component, it meets the original dimensional and torque specifications required for proper assembly on these machines. Fitment covers the RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N ), so confirming your serial number range before ordering ensures an exact match. DHS Equipment supplies this part direct, so you can be confident you are receiving the correct hardware for your roller.
Key Features
- OEM-Grade Thread Specification — Manufactured to the exact M5 thread pitch and tolerance required for secure fastening on RAMMAX roller assemblies, eliminating the risk of cross-threading or improper seating.
- Drop-In Hardware Replacement — Matches the original hex profile and drive size, so it seats correctly with standard tooling during reassembly without any modification to mounting points.
- Confirmed Roller Compatibility — Verified fitment for RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) walk-behind RAMMAX rollers.
- Structural Integrity Under Vibration — A properly torqued fastener keeps critical components secured during the continuous vibration loads generated by compaction work; a worn or incorrect nut can lead to loosening and component shift during operation.
- Genuine Multiquip OEM Part — Sourced directly through the Multiquip OEM supply chain, ensuring the part number 40028200 matches the current production specification for these roller models.
A hex nut is a threaded fastener that clamps and secures components together by pairing with a bolt or stud to create a clamped joint. On vibratory walk-behind rollers like the RAMMAX RW series, fasteners are subjected to constant vibration and mechanical stress during operation, making correct thread engagement and torque retention critical. When a hex nut is worn, stripped, or incorrectly sized, it can allow connected components to shift or detach, compromising both the structural integrity of the machine and operator safety.
