The Multiquip 57131 is a genuine OEM Hex Nut 12MM DIN 934 Class A designed for Multiquip RAMMAX roller models including RW1404MR, RW3010, RW1504HF, and P33/24 series equipment. Sourced directly from Multiquip, this fastener meets the original design specification for the applications it was built to serve. Confirm your model and serial number against the fitment notes to ensure correct application — particularly for the RW1404MR, which has a serial number break at S/N 326075, and the RW1504HF, which applies up to S/N.
Key Features
- Genuine OEM Fastener Grade — Certified DIN 934 Class A specification ensures the correct thread engagement, torque capacity, and clamping force for structural and mechanical fastening points on Multiquip rollers.
- Direct-Fit 12MM Threading — Matches the original bolt pattern and thread pitch, so installation seats correctly without reworking mating hardware or fastener positions.
- Broad Roller Fitment — Compatible with RW1404MR (S/N 326075 and up), RW3010, RW1504HF (up to S/N 1534188), and P33/24 HHMR-BD with Blade configurations.
- Structural Integrity Under Load — A properly torqued DIN 934 Class A hex nut maintains clamp load through vibration cycles; a worn, stripped, or wrong-spec nut risks joint loosening and component shift during compaction passes.
- Serial Number Fitment Breaks Noted — Fitment data includes specific S/N breakpoints for the RW1404MR and RW1504HF, so verify your machine's serial number before ordering to avoid misapplication.
A hex nut is a standard internally threaded fastener used to secure bolted joints throughout the roller's structural and mechanical assemblies. On vibratory compaction equipment like the RAMMAX roller series, fasteners are subjected to constant vibration and dynamic load cycling, which places higher-than-average demands on thread integrity and clamp retention. Using a correctly graded, OEM-specified nut such as the DIN 934 Class A 12MM ensures the joint maintains its clamping force over time — an under-spec or incorrect fastener can back off under vibration, leading to loosened assemblies, misaligned components, or accelerated wear on surrounding hardware.
