The Multiquip HZ40028400 is a genuine OEM Copper Hex Nut designed for the RW1404, RW1404MR, and RW1504HF series walk-behind rollers. As a direct OEM replacement, this nut is manufactured to the exact material grade and thread specification required by these machines. Confirmed fitment includes RW1404MR units at S/N 326075 and up, RW1504HF units up to S/N, and standard RW1404 models. Sourced directly through Multiquip's authorized parts program, HZ40028400 delivers the confidence of a factory-matched component.
Key Features
- Copper Construction for Corrosion Resistance — Copper material provides superior resistance to corrosion and galling, critical for fasteners exposed to moisture and vibration in roller applications.
- Exact Thread Match — Engineered to the precise thread pitch and hex dimensions of the original fastener, ensuring full engagement with mating components without rework.
- Confirmed Fitment for RW-Series Rollers — Verified for RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) walk-behind roller models.
- Genuine OEM Quality — Sourced directly from Multiquip, meeting the same material and dimensional standards as the nut installed at the factory — no guesswork on grade or sizing.
- Maintains Proper Fastener Torque Retention — A correctly specified hex nut holds torque under the continuous vibration loads generated during compaction work, preventing loosening and component shift.
A hex nut is a threaded fastener used to secure components together by threading onto a bolt or stud and tightening against a mating surface. In roller equipment, fasteners like the HZ40028400 are subject to continuous vibration and mechanical stress during operation, making correct material grade and thread fit essential. When a fastener is worn, stripped, or made from an incorrect material, it can allow critical assemblies to loosen, leading to misalignment or component failure during use.
