The Multiquip 57169 Hex Nut 12mm is a genuine OEM fastener designed for the RW-series RAMMAX walk-behind rollers, including the RW1403HF, RW1404, RW1404MR, and RW1810. As an OEM component sourced directly through Multiquip's authorized parts network, 57169 delivers the exact thread specification and dimensional tolerancing required for a secure, long-lasting connection. This nut is a direct-fit replacement with no additional hardware needed, and it is confirmed compatible with RW1404MR units running serial number 326075 and up. DHS Equipment supplies this part as a stocked Genuine OEM item, so you can restore your roller to full operating condition without delays.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to the exact thread pitch, hardness grade, and dimensional spec of the original hardware, ensuring consistent clamping force under machine vibration.
- Direct Bolt-On Replacement — Matches the original 12mm hex nut profile, seating correctly without rework or thread chasing on compatible RW-series roller assemblies.
- Confirmed Fitment Across Multiple RW Models — Fits RW1403HF, RW1404, RW1404MR (S/N 326075 and up), and RW1810 RAMMAX walk-behind rollers.
- Maintains Structural Integrity Under Load — A correctly torqued hex nut keeps critical assemblies tight during compaction passes; a worn or incorrect fastener risks loosening under vibration and causing premature component failure.
- Genuine Multiquip OEM Part — Carries the full Multiquip OEM designation, ensuring correct fitment and consistent performance with your existing roller hardware.
A hex nut is a fundamental fastening component used throughout roller assemblies to secure brackets, guards, shafts, and structural elements. On a vibratory walk-behind roller like the RW-series, fasteners are subjected to constant cyclical vibration forces during operation, making correct thread engagement and material grade critical. Using the wrong nut — or one with incorrect dimensional specs — can result in loosening, stripped threads, or component separation during operation, creating both a safety concern and an expensive repair.
