The Multiquip 57156 Hex Nut 12mm 1.5 is a genuine OEM fastener designed for Multiquip RAMMAX walk-behind roller models including RW1403HF, RW1404, RW1404MR, RW1504HF, and RW1810. As a direct OEM replacement, part 57156 meets the original engineering specifications for thread pitch and material grade — ensuring it seats and torques correctly without guesswork. Sourced directly through authorized distribution, this nut is the same component installed at the factory and is a straightforward like-for-like swap on compatible roller models.
Key Features
- OEM-Grade Fastener Material — Manufactured to the original 12mm x 1.5 thread specification, delivering the correct clamping force and corrosion resistance required for compaction equipment service environments.
- Direct Drop-In Replacement — Threads directly into the same position as the original hardware with no rethreading, chasing, or modification to mating components needed.
- Broad Roller Compatibility — Confirmed fitment across RW1403HF, RW1404, RW1404MR (including S/N 326075 and up), RW1504HF (up to S/N 1534188), and RW1810 RAMMAX roller models.
- Correct Torque Retention — A properly specified fastener maintains critical joint integrity under the continuous vibration loads generated during roller operation, preventing loosening or component shift during use.
- Genuine Multiquip OEM Part — Supplied as an authentic replacement under part number 57156, eliminating any uncertainty about thread pitch compatibility or dimensional fit.
A hex nut is a threaded fastener used to clamp and secure components together at a bolted joint. On vibratory roller equipment, fasteners are subjected to persistent vibration and dynamic loading throughout every work cycle, which places higher stress on hardware than in static applications. When a nut is worn, cross-threaded, or the incorrect specification, it can fail to hold the required clamping load, leading to joint loosening, component movement, and potential damage to surrounding parts. Using the correct OEM-specified replacement ensures the joint performs as originally engineered.
