The Multiquip 57171 is a genuine OEM Hex Nut 12mm designed for the RW1403HF, RW1404MR, RW1504HF, and P33/24 series walk-behind rollers. As a direct OEM replacement sourced through Multiquip's authorized parts network, the 57171 meets the same material and dimensional standards as the hardware originally installed at the factory. This nut is confirmed compatible with the RW1404MR (S/N 326075 and up), RW1403HF, RW1504HF (up to S/N ), P33/24 HHMR-BD with Blade, and P33/24 FR/FC/FCR roller configurations. Ordering by part number 57171 ensures you receive the correct 12mm hex fastener for your specific machine.
Key Features
- OEM-Grade Fastener Material — Manufactured to the same hardness and thread specification as the original hardware, ensuring consistent clamping force and corrosion resistance under field conditions.
- Correct 12mm Thread Sizing — Sized to engage mating threads without modification, installing directly in place of the original nut on RW and P33/24 series roller assemblies.
- Broad Roller Series Compatibility — Fits RW1403HF, RW1404MR (including S/N 326075 and up), RW1504HF (up to S/N 1534188), P33/24 HHMR-BD with Blade, and P33/24 FR/FC/FCR variants.
- Maintains Secure Assembly Integrity — A properly torqued hex nut keeps critical roller components clamped and aligned; a worn, stripped, or incorrect fastener can lead to loosening under vibration and premature component failure.
- Genuine OEM Part — Supplied directly through the Multiquip authorized parts network, so the part number, specification, and fitment are verified against current OEM documentation.
A hex nut is a standard threaded fastener used to clamp and retain components within a mechanical assembly. On walk-behind rollers like the RW and P33/24 series, hex nuts are found throughout the drivetrain, handle, blade, and frame assemblies, holding parts under constant load and vibration. When a hex nut stretches, strips, or is replaced with an incorrect size, it can allow movement between joined components, accelerating wear on mating parts and potentially creating an unsafe operating condition. Using the correct OEM-specified fastener — the right thread pitch, diameter, and material grade — is the simplest way to maintain the integrity of the assembly it secures.
